Bad news: The Mushroom Jazz guy is prominently involved. But even if Mark Farina’s snoozy house series leaves you cold, it’ll be swell to see somebody — anybody — onstage again at the beleaguered Greenpoint spot, shuttered since August due to various neighborly unpleasantries. Very very doubtful all Studio B’s legal/community issues have been magically solved, and things are still in flux there: As Annie Fischer just noted in the Voice, Justine D., the club’s events coordinator and talent buyer, resigned last week. Perhaps all this will only serve to make the comeback more spectacular, though. The schedule is here: Derrick Carter helms the grand reopening this Friday, Farina takes over a week later on the 24th, and most intriguingly, in between, on Wednesday the 22nd, Immortal Technique and Dead Prez preside over a “Ghetto Metal” party. How can the neighbors not love that?
