This was the 28th of the ca. 2003 "Proto Creel Pone" titles, replicating the mythic 1972 German Odeon Quadruple-LP Boxed Set of recordings by the Composer-Improviser-Performer led Ensemble Musica Negativa (including de facto leader Rainer Riehn, Gerhard Stäbler, Peter Kowald, Paul Knill - whose EMS Synthi A stylings throughout are simply a joy, Boy Raaijmakers, Heinz-Klaus Metzger, and dozens of others) of then cutting-edge works by John Cage (including "Credo In Us", "Imaginary Landscape No. 1", "Concerto For Piano And Orchestra / Solo For Voice I / Solo For Voice II", & "Rozart Mix"), Earle Brown ("October 1952", "November 1952", "December 1952", "MM - 87", "MM - 135 March 1953", "Music For 'Trio For Five Dancers' June 1953", "1953", & "Four Systems"), Christian Wolff ("In Between Pieces For Three Players" & "Electric Spring 2"), Morton Feldman (the barely-there trio of "For Franz Kline", "The Straits Of Magellan" & "Between Categories"), & Toshi Ichiyanagi ("Sapporo" & the blistering "Life Music"), culminating in a dedicated LP of conversations involving Cage, Wolff, Feldman, & Brown with Metzger & Hans G. Helms.

True to the original, this Creel Pone edition includes recreations of both inserts: "Conversations with John Cage, Christian Wolff, & Hans G. Helms • Morton Feldman, Earle Brown, and Heinz-Klaus Metzger in Discussion" (a 16-page transcription of the fourth record, with English in the left column, German on the right) then "Versuch Über Prärevolutionäre Musik • Essay On Prerevolutionary Music" (ditto, 16-pages of writings & notes in German, then English by Heinz-Klaus Metzger) both on 24 lb. "Natural White" linen stock (hope you have the Fresnel Magnifying Lens from either the "Creelpolation" or "Found On The Elevator" handy!) both in a separate sleeve/pouch (no more "P.C.P. Bulge!")
