Aaron Bruno’s tireless curiosity for new sounds makes AWOLNATION’s second album just as gleefully and thrillingly unpredictable as its predecessor. Dance beats and buzzing synths meet the grand arrangements of ‘70s prog rock, and shouted choruses give way to vocal harmonies reminiscent of Queen's and The Beach Boys'. “Hollow Moon (Bad Wolf)” converts sleek synth-pop into a towering wall of sound, and the rousing “I Am” is a defiant statement of purpose, while the moody, industrial-tinged “Run” burrows deep into the darkest corners of the subconscious.
