The Twin Cities are laden with experimental rock bands nowadays, but far too many forget the rock half of the equation. On its second full-length CD, local freak-out specialists Skye Klad incorporate as much from Black Sabbath and the Stooges as they do from arty innovators such as Can or Sonic Youth. The quartet blends droning, fuzzed-out guitars with throbbing, pulsating rhythms in songs like “Sunwheel” and “Little Nemo,” which sound like soundtrack music to a midnight screening of “Apocalypse Now.” Frontman Jason Kesselring’s deep, Nick Cave-like vocals are sinister enough to make a cover of Irving Berlin’s “Blue Skies” seem dark and foreboding. Even when the band takes its psychedelia so far as to title a song “Absynthe Opaline,” the members sound like they’re having fun, with tongues partially planted in cheek. Between bong hits, that is.
