If you have to be experience a 4.7 tremor, no better place than in Royce Hall listening to the marvelous Los Angeles Chamber Orchestra. Just before they were to play de Falla Ritual Fire Dance from El amor brujo, LA experienced a news worthy quake.
I thought to myself, I've lived through quite a few shakes, including the catastrophic 1989 Bay Area quake, but the way Royce Hall rattled, oh, it looked like the BIG one. Though a mere 4.7 on the richter scale, it seemed closer to 5.5. Even so, the orchestra paused for a few seconds and like pros, they resumed playing two move lovely pieces.
