Four new commissioned works by Chris Cutler, Andzrej Karpinski, Nick Sudnik and Alessandro Monti performed on Futurist conceptualist Luigi Russolo's "Intonarumori", unique boxes capable of mechanically creating sounds including roars, thunderings, explosions, hissing, whistling, puffing, mumbling, muttering, gurgling, screeching, creaking, buzzing, crackling and scraping.

Part of the Henry Cow boxset, now available for individual purchase, compiled from live recordings, radio transcription, or early recordings, remastered and presented to give a complete look at the history of Henry Cow.
