There’s still time to nominate local icons for Best of D.C.

A good deal more varied than its early AmphRep jackhammering, Helmet‘s Betty dabbles with jazz, blues, and dub, achieving something akin to depth. But noise addicts can rest assured: Live, the new material will probably sound like building demolition anyway. Casper Brötzmann Massaker opens tonight and Wednesday at 8:45 p.m. at the 9:30 Club, 930 F St. NW. $15. (202) 393-0930. (Steve Kuhn)
