The 7th Ave. home in the ’80s and early ’90s of Gil Evans’ last orchestra, David Murray’s octets, Abdullah Ibrahim’s bands, Lester Bowie’s Brass Fantasy and other avant-gutsy acts closed last night (Oct. 24) without notice or fanfare. Sweet Rhythm nee Sweet Basil was one of the coolest spots to listen, drink and hang out in Greenwich Village, a wood-paneled room with fine sound, sightlines, bookings and bartender, but it never recovered from what its most recent owner described as a post-9/11 decline in street traffic, competition from nearby clubs offering lesser music at no cover charge, and disinterest among the young in jazz.
