This was the 32nd of the "Proto Creel Pone" (P.C.P.) titles, focusing on the consecutive string of Advance Recordings (the same that issued the lone LP by Richard Maxfield, the Robert Ashley / Gordon Mumma / George Cacioppo / Donald Scarvada "Music From The ONCE Festival" set, & of course Harold Budd's "The Oak Of The Golden Dreams") compilations assembled & issued yearly around the American Society Of University Composers (ASUC) conferences between 1978 & 1982, housed alongside the preceding & quite rare (I've never seen another copy aside from the one that fell into my hands back in the early 2000s) "Supplement to Proceedings 7/8" LP covering the 1972/73 events. 

Collecting works by a litany of regional composers largely working within Electronic Music, Computer Music (which is referred to as "Computor Music" throughout; the term then being something of a neologism, to give you an idea of the timeframe at work here), Extended Techniques, and/or largely outside of idiom including Leslie Bassett, Allan Blank, Richard Brooks, David Cohen, Steven R. Gerber, Walter S. Hartley, James J. Hartway, Sidney Hodkinson, Reed K. Holmes, Hubert S. Howe, Jr., Donald MacInnis, Barton McLean, John Melby, Lawrence Moss, Robert Newell, Stuart Smith, Robert Stern, Eric Stokes, Robert Stewart, Bruce Taub, Joan Tower, Reynold Weidenaar, & Yehuda Yannay, these collections provide an alternate understanding of the landscape of contemporary composition as approached by those intimately familiarly with then-current repertoire in an educational capacity, resulting in some, frankly, wild & unconvential ideas that frequently push known envelopes. 

This Creel Pone edition comes as a quadruple-disc set in the familiar glossy six-panel diagonal "Six Record" layout, with an additional six-page insert offering monochrome detail & liners of the Advance titles & the "Mail-In" sheet one would have used to acquire the earlier collection... along with a separate, hand-stapled 8-page booklet covering the "Compositional Approaches to Computer Music" panel discussion moderated by Melby between Cohen,  Howe Jr., & MacInnis with Charles Dodge & Barry Vercoe at the 1972 event, branching out to separate topics by Cohen ("Computer Performance as Model and Challenge") & Howe Jr. ("Compositional Technique in Computer Sound Synthesis").

Once you hold this in your hands you'll understand why the C.P. P.T.B. took forever to cycle around to this 20th Anniversary "Réédition" given all of the moving parts; easily one of the more involved titles, matching only the recreation of the Ensemble Musica Negativa ([CP 000.28 CD]) set in production-value!
