On the band's fifth LP, guitarist Tim Sult plays like an orphaned Allman Brother, coming with greasy, beer-battered riffs by turns funky and fierce. Dusky, reverb-saturated rural blues ("Regulator") and goose-stepping, Grand Funk-worthy stompers ("Army of Bono") sweat it up alongside the baked boogie that's spawned Clutch's cult following. The latter half loses a little steam, but you'll still have a blast letting out the Clutch and stepping on the gas.
