One of dance/electronica's fastest-rising stars -- and also one of its most baffling -- Canada's Joel Zimmerman only started spinning and recording as DeadMau5 ("dead mouse") less than five years ago, and just released his mostly instrumental debut artist album a year ago. But he already ranks in the upper tier in international DJ polls and has garnered several industry awards. He's also become something of a staple at the 9:30 Club, returning for his third set of gigs in just over a year. He's supporting his sophomore set, For Lack Of A Better Name, which is slightly less spare and blippy than the debut. Thursday, July 29, is the only night of three that is not already sold out. Doors at 7 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $40. Call 202-265-0930 or visit 930.com.
