Graham, the show on 3/14 was not a hiphop show; bands were Centaurs of Attention, Blesst Chest, and the Jelly Project. That show was not broken up (nor was the show on 3/22) but the venue was cited and fined.
CORRECTION: Regarding my previous comment—a member of Centaurs of Attention tells me that their show on 3/14 WAS in fact shut down by the fire marshal.
Centaurs of Attention should quit horsing around like it's their first rodeo. No need to stirrup trouble and saddle some single stall venue with a load of manure.
