DJ/producer/wild-man The Gaslamp Killer (AKA William Bensussen) might have been pushed back an hour or so (he didn't start until 2.30am) but the crowd at Roxanne on Friday were stomping around to the dulcet tones of Harmonic 313, Spoonbill and others throughout the night. It was an evening of dirty, heavy dubstep debauchery and all the dancers were proper schvitzy by the end.
