Tio Bitar leads off with a wordless guitar scream and a blaze of rhythm section, knocking a hole in the wall of sound just as quickly to let in an otherworldly flute melody that's pure Ian Anderson. As modern rockers go, Dungen makes no bones about reaching back into the past to embrace both Black Sabbath's beefy parallel riffing and Jethro Tull's flights of jazzy digression. This is the second U.S. release for the Swedish band, following 2005's Ta Det Lugnt and as their name implies, Dungen are heavy, metallic, and occasionally impenetrable. Though "psychedelic" is the main reference point that comes to mind, and songs like "C Visar Vägen" and "Familj" display as much structural schizophrenia and loopy, lovely melodicism as a Donovan record hopped up on amphetamines, don't mistake Dungen for an exercise in rose-colored nostalgia--there's more than a twinge of new millennium nervousness in this dense and quite compelling record.
