Watch Django Reinhardt & Stéphane Grappelli Play Masterfully Together in Vivid Color (1938)

Few jazz gui­tarists today could claim to be entire­ly free of the influ­ence of Djan­go Rein­hardt. This despite the fact that he lost the use of two fin­gers — which ulti­mate­ly encour­aged him to devel­op a dis­tinc­tive play­ing style — and that he died 68 years ago. The unfor­tu­nate abbre­vi­a­tion of Rein­hardt’s life means that he nev­er built a sub­stan­tial body of solo work, though he did play on many record­ed dates that include per­for­mances along­side Cole­man Hawkins and Ben­ny Carter. It also means that he left even less in the way of footage, though we do get a crisp and illu­mi­nat­ing view of him and his gui­tar in the 1938 doc­u­men­tary short “Jazz ‘Hot,’ ” pre­vi­ous­ly fea­tured here on Open Cul­ture.

“Jazz ‘Hot’ ” also fea­tures vio­lin-play­ing from Stéphane Grap­pel­li, who found­ed the group Quin­tette du Hot Club de France with Rein­hardt in 1934. As they deep­ened their knowl­edge of jazz, the two influ­enced each oth­er so thor­ough­ly as to devel­op their own style of music.

Grap­pel­li lived long enough to play with the likes of Jean-Luc Pon­ty, Paul Simon, Yo Yo Ma, and even Pink Floyd. Still, more than a few jazz fans would sure­ly claim that none of his pro­fes­sion­al col­lab­o­ra­tors was more impor­tant to his musi­cal for­ma­tion than Rein­hardt. Now you can see them play­ing togeth­er in col­or, and fair­ly real­is­tic col­or at that, in the clip at the top of the post.


The orig­i­nal black-and-white footage (which appears just above) was col­orized with DeOld­ify, a deep learn­ing-based appli­ca­tion devel­oped to restore pho­tographs and motion pic­tures from bygone times. Per­haps you’ve seen the pre­vi­ous DeOld­ify col­oriza­tion projects we’ve fea­tured here, which run the gamut from musi­cal num­bers in Stormy Weath­er and Hel­lza­pop­pin’ to scenes of 1920s Berlin and even an 1896 snow­ball fight in Lyon. Grant­ed access to a time machine, more than a few jazz-lovers would no doubt choose to go back to the Paris of the 1930s to see the Quin­tette du Hot Club de France in action. Tech­nol­o­gy has yet to make that a viable propo­si­tion, but it’s giv­en us a next-best-thing that no appre­ci­a­tor of jazz gui­tar — or jazz vio­lin — could fail to enjoy.

How Randy Bachman Found His Stolen Favorite Guitar After 45 Years, with the Help of Facial-Recognition Software

Facial-recog­ni­tion tech­nol­o­gy has come into its own in recent decades, though its imag­ined large-scale uses do tend to sound trou­bling­ly dystopi­an. Still, some of its actu­al suc­cess sto­ries have been pleas­ing indeed, few of them so much as the one briefly told in the video above by Bach­man Turn­er Over­drive’s Randy Bach­man. Its pro­tag­o­nist is not Bach­man him­self but one of his gui­tars: a 1957 Gretsch 6120 Chet Atkins, a mod­el named after the star Nashville gui­tarist. “This is the first real­ly good expen­sive elec­tric gui­tar I got,” he says, adding that he “played it on many, many BTO hits, and in 1975 it was stolen from a Hol­i­day Inn hotel room in Toron­to.”

“The dis­ap­pear­ance trig­gered a decades-long search,” writes Todd Coyne in a fea­ture at CTV News. “Bach­man enlist­ed the help of the RCMP” — also known at the Moun­ties — “the Ontario Provin­cial Police and vin­tage instru­ment deal­ers across Cana­da and the Unit­ed States. It also trig­gered what Bach­man now rec­og­nizes as a mid-life cri­sis,” result­ing in his even­tu­al pur­chase of 385 Gretsch gui­tars. Those includ­ed a dozen 6120s from the 1950s, but none of them were the one he bought at age 20 from Win­nipeg Piano. He must have giv­en up hope by the time the mes­sage arrived: “I found your Gretsch gui­tar in Tokyo.”

The sender, an old neigh­bor of Bach­man’s, had in fact found the Gretsch on Youtube. In the video below, made for Christ­mas 2019, a Japan­ese gui­tarist named Takeshi plays “Rockin’ Around the Christ­mas Tree” on an orange 6120 that Bach­man imme­di­ate­ly rec­og­nized as his long-lost favorite instru­ment. Coyne writes that the neigh­bor “had used some old pho­tographs of the gui­tar and rejigged some facial-recog­ni­tion soft­ware to iden­ti­fy and detect the unique wood-grain pat­terns and lines of cracked lac­quer along the instrument’s body,” as seen in the orig­i­nal video for BTO’s “Lookin’ Out for #1.” Sub­se­quent­ly, he “ran scans of this unique pro­file against every image he could find of an orange 1957 Chet Atkins gui­tar post­ed online over the last decade and a half.”

Per­sis­tence, at least in this case, paid off. But since Takeshi felt near­ly as strong a con­nec­tion to the gui­tar as Bach­man did, an arrange­ment had to be made. With the Japan­ese wife of his son Tal (also a musi­cian, best known for the 1990s hit “She’s So High”) act­ing as inter­preter, he nego­ti­at­ed with Takeshi the terms of an exchange. As Bach­man tells it, “He said he would give me back my gui­tar, but I had to find him its twin”: the same mod­el — of which only 35 were made in 1957 — in mint con­di­tion with all the same parts and no addi­tion­al mod­i­fi­ca­tions. And for a mere thir­ty times the $400 price he orig­i­nal­ly paid, he even­tu­al­ly found that twin. Now all that remains, as soon trav­el restric­tions ease between the U.S. and Japan, is for Bach­man and Takeshi to meet up at the Gretsch fac­to­ry in Nagoya, play a gig togeth­er, and take care of busi­ness.

How Neal Stephenson’s Sci-Fi Novel Snow Crash Invented the “Metaverse,” Which Facebook Now Plans to Build (1992)

What­ev­er the ben­e­fits and plea­sures of our cur­rent inter­net-enriched world, one must admit that it’s not quite as excit­ing as the set­ting of Snow Crash. Orig­i­nal­ly pub­lished in 1992, that nov­el not only made the name of its author Neal Stephen­son, it ele­vat­ed him to the sta­tus of a tech­no­log­i­cal Nos­tradamus. It did so, at least, among read­ers inter­est­ed in the inter­net and its poten­tial, which was much more of a niche sub­ject 29 years ago. Of the many inven­tions with which Stephen­son fur­nished Snow Crash’s then-futur­is­tic 21st-cen­tu­ry cyber­punk real­i­ty, few have cap­tured as many techie imag­i­na­tions as the “meta­verse,” an enor­mous vir­tu­al world inhab­it­ed by the avatars of its users.

“Lots of oth­er sci­ence fic­tion media includes meta­verse-like sys­tems,” writes The Verge’s Adi Robert­son, but “Stephenson’s book remains one of the most com­mon ref­er­ence points for meta­verse enthu­si­asts.” This holds espe­cial­ly true in Sil­i­con Val­ley, where, as Van­i­ty Fair’s Joan­na Robin­son puts it, “a host of engi­neers, entre­pre­neurs, futur­ists, and assort­ed com­put­er geeks (includ­ing Ama­zon C.E.O. Jeff Bezos) still revere Snow Crash as a remark­ably pre­scient vision of today’s tech land­scape.” It’s rumored that Face­book CEO Mark Zucker­berg will soon announce his com­pa­ny’s intent to change its name to one that bet­ter suits its own long-term plan: to tran­si­tion, as Zucker­berg him­self put it, “from peo­ple see­ing us as pri­mar­i­ly being a social media com­pa­ny to being a meta­verse com­pa­ny.”

Bold though this may sound, astute read­ers haven’t for­got­ten that Snow Crash is a dystopi­an nov­el. The meta­verse it presents “is an out­growth of Stephenson’s satir­i­cal cor­po­ra­tion-dom­i­nat­ed future Amer­i­ca,” writes Robin­son, “but it’s unde­ni­ably depict­ed as hav­ing a cool side.” After all, the nov­el­’s pro­tag­o­nist is “a mas­ter hack­er who gets in katana fights at a vir­tu­al night­club,” though his vir­tu­al exis­tence com­pen­sates for a grim­mer real-world lifestyle. “In the book, Hiro lives in a shab­by ship­ping con­tain­er,” Stephen­son says, “but when he goes to the Meta­verse, he’s a big deal and has access to super high-end real estate.” This may sound faint­ly rem­i­nis­cent of cer­tain online worlds already in exis­tence: Sec­ond Life, for exam­ple, whose hey­day came in the ear­ly 2010s.

Though pre­sum­ably more ambi­tious, Zucker­berg’s vision of the meta­verse remains, for the moment, broad­ly defined: it will con­sist, he’s said, of “a set of vir­tu­al spaces where you can cre­ate and explore with oth­er peo­ple who aren’t in the same phys­i­cal space as you.” But as The Verge’s Alex Heath notes in an arti­cle on Face­book’s impend­ing name change, the com­pa­ny “already has more than 10,000 employ­ees build­ing con­sumer hard­ware like AR glass­es” — glass­es, that is, for aug­ment­ed real­i­ty, the over­lay­ing dig­i­tal ele­ments onto the real world — “that Zucker­berg believes will even­tu­al­ly be as ubiq­ui­tous as smart­phones.” It’s not impos­si­ble that he could be lead­ing the way toward the thrilling, dan­ger­ous, and often hilar­i­ous vir­tu­al world Snow Crash held out to us — and in whose absence we’ve had to make do with Face­book.

Slot Machine Age: A 1964 British Newsreel Angsts Over Whether Automated Machines Will Displace People

When Amer­i­cans hear the phrase “slot machine,” they think of pen­sion­ers com­pul­sive­ly pulling levers day and night in Las Vegas. But when the British hear it, a much less bleak vision comes to their minds: the auto­mat­ed dis­pen­sa­tion of cig­a­rettes, cof­fee, gro­ceries, and even entire meals. Or at least such a vision came to the minds of Britons back in 1964, the year of the British Pathé news­reel above. With its bril­liant col­ors and jazzy score, Slot Machine Age proud­ly dis­played to the view­ing pub­lic the range of coin-oper­at­ed won­ders already mak­ing their way into dai­ly life, from pay phones and pin­ball machines to shoe-buffers and bot­tle-recy­cling sta­tions.

“This inven­tion, this brain­child of the boffins, has cre­at­ed a new dis­ease,” declares the announc­er: “slot machine fever.” Again, this has noth­ing to do with gam­bling, and every­thing to do with automa­tion. Near­ly 60 years ago, buy­ing some­thing from a machine was a nov­el­ty to most peo­ple in even the most high­ly indus­tri­al­ized coun­tries on Earth.

Yet even then the automat, where din­ers pulled all their dish­es from coin-oper­at­ed win­dows, had in cer­tain cities been an insti­tu­tion for decades. Alas, such estab­lish­ments did­n’t sur­vive the explo­sion of fast food in the 1970s, whose busi­ness mod­el made use of more, not less, human labor.

But in the 1960s, the age of the robot seemed well on its way — so much so that this phrase titles anoth­er, slight­ly lat­er British Pathé pro­duc­tion show­cas­ing a “semi-com­put­er­ized ver­sion of the dumb­wait­er” being tried out in hotel rooms. From it the film’s hon­ey­moon­ing cou­ple extract cock­tails, peanuts, tooth­paste, and “that last cig­a­rette of the day.” It even offers read­ing mate­r­i­al, a con­cept since tried again in France, Poland, San Fran­cis­co, and an eccen­tric book­store in Toron­to, but the glo­ri­ous age of all-around con­ve­nience pre­dict­ed in these news­reels has yet to mate­ri­al­ize. We cit­i­zens of the 21st cen­tu­ry are in many cas­es hard­ly pleased, but rather anx­ious about what we see as our grow­ing depen­dence on automa­tion. Still, with the coro­n­avirus-induced vogue for con­tact-free pay­ment and din­ing, per­haps it’s time to give the automat anoth­er chance.

Gustav Klimt’s Masterpieces Destroyed During World War II Get Recreated with Artificial Intelligence

A cen­tu­ry after the death of Gus­tav Klimt, his art con­tin­ues to enrap­ture its view­ers. Maybe it has enrap­tured you, but no mat­ter how deep you’ve gone into Klimt’s oeu­vre, there are three paint­ings you’ve only ever seen in black and white. That’s not because he paint­ed them in that way; rich and bril­liant col­ors orig­i­nal­ly fig­ured into all his work, the most notable usage being the real gold lay­ered onto his best-known paint­ing, 1908’s The Kiss. In the year before The Kiss, he com­plet­ed an even more ambi­tious work: a series of paint­ings com­mis­sioned for the Uni­ver­si­ty of Vien­na’s Great Hall, meant to rep­re­sent the fields after which they were titled: Phi­los­o­phy, Med­i­cine, and Jurispru­dence.

Klimt’s “Fac­ul­ty Paint­ings,” as they’re now known, struck crit­ics at the time as pieces of “per­vert­ed excess.” Such charges must have been noth­ing new to Klimt, for whom unabashed eroti­cism and sub­jec­tive views of real­i­ty — nei­ther par­tic­u­lar­ly in fash­ion in the insti­tu­tions of ear­ly 20th-cen­tu­ry Vien­na — con­sti­tut­ed basic artis­tic prin­ci­ples.

Ulti­mate­ly, Klimt him­self bought Phi­los­o­phy, Med­i­cine, and Jurispru­dence back, and by the end of the Sec­ond World War all three had found their way into the hands of the Nazis. With defeat loom­ing, they chose to burn down rather than sur­ren­der the Aus­tri­an cas­tle in which they’d been stor­ing the Fac­ul­ty Paint­ings and oth­er works of art.

With the Fac­ul­ty Paint­ings sur­viv­ing only in black-and-white pho­tographs and scanty descrip­tions, gen­er­a­tions of Klimt enthu­si­asts have had to imag­ine how they real­ly looked. Now, Google Arts & Cul­ture and Vien­na’s Belvedere Muse­um have joined forces to fig­ure out to a greater degree of cer­tain­ty than ever, using arti­fi­cial intel­li­gence to deter­mine what col­ors Klimt would have applied to Phi­los­o­phy, Med­i­cine, and Jurispru­dence based on in-depth analy­ses of the rest of his work. You can get an overview of the process from the short video at the top of the post, and you can read about it in more detail at Google Arts & Cul­ture.

“Klimt’s three Fac­ul­ty Paint­ings were among the largest art­works Klimt ever cre­at­ed and in the field of Sym­bol­ist paint­ing they rep­re­sent Klimt’s mas­ter­pieces,” says Belvedere cura­tor Dr. Franz Smo­la in a Google Arts & Cul­ture blog post. “The col­ors were essen­tial for the over­whelm­ing effect of these paint­ings, and they caused quite a stir among Klimt’s con­tem­po­raries. There­fore the recon­struc­tion of the col­ors is syn­ony­mous with rec­og­niz­ing the true val­ue and sig­nif­i­cance of these out­stand­ing art­works.” The project comes as just one part of Klimt vs. Klimt: The Man of Con­tra­dic­tions, an online ret­ro­spec­tive fea­tur­ing more than 120 of the artist’s works avail­able to view in aug­ment­ed real­i­ty, as well as an ultra-high-res­o­lu­tion scan of The Kiss. Klimt’s paint­ings may no longer shock us, but they still have much to show us.

A Brilliant Demonstration of Magnets & the Promise of Levitating Trains (1975)

For a brief time in the 1980s, it seemed like trains pow­ered by maglev — mag­net­ic lev­i­ta­tion — might just solve trans­porta­tion prob­lems every­where, maybe even replac­ing air trav­el, there­by elim­i­nat­ing one of the most vex­ing sources of car­bon emis­sions. Maglev trains don’t use fuel; they don’t require very much pow­er by com­par­i­son with oth­er sources of high speed trav­el; they don’t pro­duce emis­sions; they’re qui­et, require less main­te­nance than oth­er trains, and can trav­el at speeds of 300 mph and more. In fact, the fastest maglev train to date, unveiled this past sum­mer in Qing­dao, Chi­na, can reach speeds of up to 373 miles per hour (600 kph).

So, why isn’t the plan­et criss-crossed by maglev trains? asks Dave Hall at The Guardian, cit­ing the fact that the first maglev train was launched in the UK in 1984, after which Ger­many, Japan, and Chi­na fol­lowed suit. It seems to come down, as such things do, to “polit­i­cal will.” With­out sig­nif­i­cant com­mit­ment from gov­ern­ments to reshape the trans­porta­tion infra­struc­ture of their coun­tries, maglev trains remain a dream, the mono­rails of the future that nev­er mate­ri­al­ize. Even in Chi­na, where gov­ern­ment man­date can insti­tute mass changes at will, the devel­op­ment of maglev trains has not meant their deploy­ment. The new train could, the­o­ret­i­cal­ly, fer­ry trav­el­ers between Shang­hai to Bei­jing in 2.5 hours… if it had the track.

Per­haps some­day the world will catch up with maglev trains, an idea over a cen­tu­ry old. (The first patents for maglev tech­nol­o­gy were filed by a French-born Amer­i­can engi­neer named Emile Bachelet in the 1910s.) Until then, the rest of us can edu­cate our­selves on the tech­nol­o­gy of trains that use mag­net­ic lev­i­ta­tion with the 1975 video les­son above from British engi­neer and pro­fes­sor Eric Laith­waite (Impe­r­i­al Col­lege Lon­don), who “decon­structs the fas­ci­nat­ing physics at work behind his plans for a maglev trains, which he first mod­elled in the 1940s and per­fect­ed in the 1970s,” notes Aeon. “Well-regard­ed in his time as both a lec­tur­er and an engi­neer, Laith­waite presents a series of demon­stra­tions that build, step by step, until he final­ly unveils a small maglev train mod­el.”

Laithwaite’s small-scale demon­stra­tion would even­tu­al­ly cul­mi­nate in the first com­mer­cial maglev train almost a decade lat­er at Birm­ing­ham Air­port. Here, he begins where sci­ence begins, with an admis­sion of igno­rance. “Per­ma­nent mag­nets are dif­fi­cult things to under­stand,” he says. “In fact, if we’re absolute­ly hon­est with our­selves, we don’t under­stand them.” The good pro­fes­sor then briskly moves on to demon­strate what he does know — enough to build a lev­i­tat­ing train. Learn much more about the his­to­ry and tech­nol­o­gy of maglev trains at How Stuff Works, and keep your eyes on the North­east Maglev project, a devel­op­ing Super­con­duct­ing Maglev train that promis­es trav­el between New York and Wash­ing­ton, DC in one hour flat.

On Sun­day night, Frances Hau­gen, a for­mer Face­book data sci­en­tist, appeared on 60 Min­utes and revealed that she left the com­pa­ny with a trove of pri­vate Face­book research–research which shows, she con­tends, that the com­pa­ny know­ing­ly ampli­fies hate, mis­in­for­ma­tion and polit­i­cal unrest, all to keep peo­ple engaged and out­raged, and thus their adver­tis­ing mon­ey machine rolling. And that’s just the tip of the ice­berg.

Ini­tial­ly, she gave the com­pa­ny’s leaked doc­u­ments to the Wall Street Jour­nal, and they became the basis of the pod­cast series The Face­book Files. Accord­ing to the Jour­nal, “Time and again, the doc­u­ments show, Facebook’s researchers have iden­ti­fied the platform’s ill effects. Time and again, despite con­gres­sion­al hear­ings, its own pledges and numer­ous media exposés, the com­pa­ny didn’t fix them. The doc­u­ments offer per­haps the clear­est pic­ture thus far of how broad­ly Facebook’s prob­lems are known inside the com­pa­ny, up to the chief exec­u­tive him­self.”
