With a name that translates roughly to "stranglehold" in Norwegian, this sextet has spent the last six years cultivating a sound that feels like a mixture of black metal and the Stooges, Cave In and Converge. Fittingly, the frontman of that last act, Kurt Ballou, produced Kvelertak's latest album, 2013's Meier, which bears artwork from a like-minded musician, Baroness's John Baizley. With an oddly and refreshingly balanced combination of rawness, melody and heaviness — not to mention aggression and psychedelia — Kvelertak also manages to invoke an American Southern-rock vibe without beating that retro aesthetic into the ground. With songs propelled by a momentum that's broken only by moments of lingering atmospherics, like the eye of a storm, this outfit sways as much as it rocks.
