I am betting you went to the Necterine Ballroom....it is(or was) a Gay Bar on Tuesdays and Fridays. Looks like you picked the wrong night to go! When I lived in AA, Wednesday and Thursday nights were techno/world music. Saturday was/is "Back to the Chance" night with real rock and roll.
Used to be a super kickass rock bar, when it was the Second Chance. Much bigger too.
