LAZARUS A.D. At first listen, thrashers Lazarus A.D. sound a bit run of the mill, but the blokes pick up the slack fast. They make no bones of channeling '80s thrash, a la Testament, Slayer, where metal riffs incessantly pounce out the amps onto the pit dwellers. Their new album, Black Rivers Flow, is slated to drop this week. Also on the bill of this night of ear pounding metal mayhem: Death Angel, Bounded by Blood, and SkinKage. $17-$20.
