The Swedish trio’s raw-boned blues-rock sounds like a secret session from 1970. If you weren’t around when Zeppelin, Cream, and Hendrix first rattled rock music by pairing muscular blues rhythms to savage guitar riffs, SVVAMP re-enacts that primordial jolt. Between the distorted wah-wah solos and barreling bass-and-drum attacks, these extra-chunky performances are a feast to be relished by garage punk brats and classic rock brawlers.
