They played the 9:30 late last year, in one of those late night shows that follows one of those ridiculously early shows by a band with fans that are older or younger than average. Anyway, the way I remember it the doors were scheduled to open at 10 with the band going on at 11, but things got off to a MUCH slower start and they didn't actually hit the stage until 11:30 or midnight. Even with that late of a start, and all the delays, I'd say the club was still about 2/3 full with stage as far forward as it comes.
The concert was excellent, the grooves were tight and the crowd was into it. The lead singer is incredibly sexy, and was dressed for the evening in a skin-tight flesh-colored leotard, to which she had affixed three black cardboard bars in strategic locations. Including one attached to glasses that obscured most of her face for the entire show. One of the definite highlights was when she got the entire crowd to sing along loudly with the chorus, "Pussy pussy pussy marijuana" ... ah, good times.
Definitely worth checking out. My utterly uniformed opinion is that there's some possibility of a sellout, although probably closer to the show or on the night of if it happens at all.
