The 9:30 Club hosted a local-ish metal blowout on Thursday: Lamb of God (Richmond), Darkest Hour (D.C.), Periphery (Bethesda) and This or the Apocalypse (Lancaster, PA). The seriously high-energy performances were matched by one of the most active, enthusiastic crowds I’ve ever seen at a D.C. show.
