Six Organs mainstay Ben Chasny has become one of the high shamen of the US psychedelic underground, disseminating his hairy vision between at least three bands and a couple of genres over the past decade. His umpteenth album begins with a sonic white-out called Waswasa – a thrilling myocardial infarction of guitar more in keeping with another of his bands, Comets on Fire, who are, in fact, on board here. How Chasny tells his sprawling, incandescent guitar solos apart, we may never know; this is an album for frenziedly colouring outside the lines. But there is calm, too, as Chasny reverts to his acoustic instincts for Your Ghost.
