Scottland's large improvising ensemble of around 20 musicians, merging backgrounds in free improvisation, jazz, classical, folk, pop, experimental musics and performance art, in a 2-CD release of a piece commissioned by the BBC and featuring pianist Marilyn Crispell and saxophist Evan Parker, written using graphic scores, through composition, photographs and artwork.

Recordings from the Glasgow Improvisers Orchestra Festival in Scotland recorded in 2013 & 2015, the 20+ piece orchestra blending acoustic, electronic and vocal instruments into incredibly diverse and rich compositions, here presenting "A Peculiar Slumber" I & II, and the impressive and large work "A Bit in the Air", both exploring words and loss of control.

The large Glasgow Improvisers Orchestra, led by Raymond MacDonald, met trombonist George Lewis in 2012 at CCA in Glasgow to record this two part work based on a set of instructions presented graphically, plus an extended free improvisation.
