I work at Davies Symphony Hall and ‘hear’ the San Francisco Symphony a lot. I put ‘hear’ in quotes because I usually ‘hear’ them from inside the lighting booth through one microphone hanging above the stage and some inexpensive speakers.
Today I went into the hall for some minor maintenance reason while the rehearsal was going on. OMG, what a sound!
I’ll tell you, live music on real instruments. There’s nothing like it!
BTW, MTT was conducting Mahler in what’s called the antiphonal setup. That is when the first and second violins are on opposite sides of the stage. No surround sound system can duplicate this!
