** Restocked, reduced price** A re-issue of the Pogus LP format with additional material taken from the same concert at the Arts Club, Chicago, USA, 25th May 1984. The difference in the music included on this CD version is the addition of Treatise '84. This, as the audience was aware, was an Amm improvisation inspired and guided, rather than dictated or controlled by Cornelius Cardew's graphic masterpiece. There is, of course, no way that this work could be identified as a composition in the accepted sense. There is no universal correlation between the symbols on the page and the sounds the musicians make. Cardew gave no indications as to what any of his graphics might represent. Later, in the Treatise Handbook he offered thoughts upon how such a musical engagement might develop. Nothing however was prescriptive.
