This wryly titled offering from Thurston Moore, Jim O’Rourke and two members of Nordic free-jazzers The Thing, among others, is a 60-minute (two-track) slab of awesomely intense, wholly improvised avant noise. It represents the appeal of extreme improv from Boredoms to Sunn O))) – thus what at first might appear as an impenetrable wall slowly opens up to reveal perversely beautiful wormholes of melody, rhythm and texture. Not for the faint-hearted or the fragile-eared – or those in shared housing, perhaps – but still hugely thrilling.
