The Shackeltons probably aren't sincere in crediting Arctic explorer Sir Ernest Shackleton as their biggest influence, and they certainly aren't discovering new musical terrain. A tight five-piece whose proficiency allows integration of several satisfying Guitar Hero modes into single songs—"Soft Heart" quickly flips an abrasive Fugazi-ish intro into sub-Franz Ferdinand alt-disco—The Shackeltons mostly have problems with the vocals. Mark Redding tends toward Jack White yelps, though he's occasionally possessed by Conor Oberst's quaver and emo poetry. "The Blood" details how Redding "found a rose picked it up by the thorns and watched the blood run down my fingertips." No excellent riffs can completely redeem that.
