You'll note a fair bit of jazz talk on the threads about favorite musicians, and Max Roach's passing was noted with a thread, etc., so there's definitely a jazz crowd here.
I listen to tons of Bill Evans, Coltrane, Davis, Dave Brubeck, Bud Powell, Thelonious Monk, Django Reinhardt, and some modern stuff like Joshua Redman and John Scofield too.
My big worry about jazz is that there are very few big jazz 'scenes', and so many people - including young musicians, especially! - have little exposure to good live jazz.
