Metal has been on an artistic resurgence of late, but the Japanese growlers Dir En Grey have been at it for decades. Their sound veers from more rock-inclined tunes to very avant-garde, and their new album "Dum Spiro Spero" is the occasion for another blistering live tour. House of Blues, 8430 Sunset Blvd., West Hollywood. 8 p.m. Fri. $29.50. hob.com.
