Formed in 1977, the freely improvising group of David Toop, Peter Cusack, Terry Day & Steve Beresford approached their performances with an extensive collection of instruments spread across the floor, allowing a vast range of expression both conventional and bewildering, collective and combative, as the group reveled in a concept of "production friction", here in never-released live recordings.

An extended improvisation interweaving acoustic and electronic instruments in a beautifully coherent evolution of mysterious and approachable sources, from the trio of Jan Bang, David Toop and Mark Wastell, combining tam tams, gongs, flutes, lapsteel, live sampling, gongs, brushes, elastic, paper and more to captivate the curious listener.
