I'm not quite back from the ISB convention yet (various flight delays have marooned me in Denver, for the moment), but I think I'm slowly coming down from the 6 days of bass insanity. Crunching the numbers, I believe I saw:

25 classical recitals (including 9 that were entirely contemporary music)
7 jazz concerts
9 solo competition performances, and 5 orchestra competition auditions
5 lecture/demonstrations
3 masterclasses

That's probably twice as many bass recitals as I saw in my entire 6 years of college and grad school. Who's counting, though?
