Hooking up with Black Key Dan Auerbach (one of rock 'n' roll's most in-demand producers), LaMontagne unleashes what is far and away his most eccentric LP to date. Though Supernova still boasts his ruminative storytelling, sonically speaking, he's chosen to explore new waters. Reminiscent of My Morning Jacket, the record is a dreamy and psychedelic fusion of rural rock ("Drive-In Movies"), neo-Tropicalismo ("Pick Up a Gun") and retro-garage ("Julia"). By album's end it becomes clear that LaMontagne possesses far more ambition than the majority of singer-songwriters considered his peers.
