Writes the LA Philharmonic on their Youtube Channel:
On March 28, 2014 at 9:09pm, a 5.1 magnitude earthquake rocked Los Angeles. The Los Angeles Philharmonic was six minutes into a performance of Ravel's "Daphnis and Chloé" with guest conductor Charles Dutoit when the quake hit. A strong jolt followed by a minute of rumbling did not unhinge the orchestra or Maestro Dutoit, and the stirring concert continued without a hitch.
