The Downtown Music Gallery is the only place you need to go.  All prog, jazz, avant, free stuff.  They have THE biggest tzadik section I have ever seen.  If I remember correctly it is across the street from CBGB's but I am not positive.  If I had more than a dial up connection I would track the address for you.
Has anyone else heard the new "Masada Recital" disc that just came out?  I think it is a great interpretation of some familiar songs from the masada book.  Mark Feldman and Sylvie Courvoisier make a formidable team.
