Over three albums, Heartless Bastards singer Erika Wennerstrom has proven herself a natural rock star — there's a bit of PJ Harvey and Robert Plant in her — with a voice that slides from trebly quaver to a fearsome, wide-mouthed roar. She's not prone to understatement: On the Ohio rockers' new album, Wennerstrom sings about traversing deserts, being lashed by hurricanes and peering "into the mountain where your desire goes." The band's sound is fuller now, with violin and banjo adding homespun accents to its garage-blues sludge on songs like "Had to Go." And the new rhythm section swerves and stomps harder than ever, making a racket worthy of Wennerstrom's voice — a veritable mountain of sound.
