The legendary collaboration between a leading American Musique Concrete composer and an instrumental ensemble directed by James Reichert where, for I think the first and to date only time, there was full integration of the written, played and manipulated sounds. The instrumental parts were derived from ╬cells' of concrete sound and in turn were electronically transformed (in Robert Moog's then state of the art studio), Then the whole mass of material was organised together. A true hybrid, and a one-off. Long out of print since it's appearance on vinyl in 1966. With two extra pieces by Tod Dockstader a new stereo version of No.7 (from the 1961 ╬8 Electronic Pieces' and very late and very different - piece from 1990 which has never escaped his studio until now. A classic and a milestone in the evolution of electronic, mediated sound.
