If you're already done with the threat of winter, this double bill—a convocation of two swampy, sludgy beasts from the South—should shake away the gray blues. Black Tusk's Taste the Sin is a crossover blast from Savannah, built as much on punk rock's roil as heavy metal's maw. With sharp riffs sculpted by distortion and powered by a relentless rhythm section, Black Tusk makes the most of its throbbing mid-tempo comfort zone. Crowbar's been doing this stuff since the late '80s, scowling the blues through smoke-and-liquor-lacerated vocals and over a metal march that lunges between poles of speed and stomp. With Broadslab and Chapel Hill's excellent MAKE. —Grayson Currin
