Orchestra Of The Upper Atmosphere aka OrchUA are an improvisation based rock group whose core octet, led by keyboardists Martin Archer and Chris Bywater, is augmented by string and horn sections, plus a 20 piece choir called Juxtavoices. All of these participants can be heard on this short extract from their second release, a 160 minute piece which applies extensive post production and arrangement to basic tracks originally improvised live.
