John Cage "The 25-Year Retrospective" Concert of the Music of John Cage / Recorded in performance at Town Hall, New York, May 15, 1958. The heavy & glossy vinyl, still in the rice paper sleeve, is visually graded in near mint condition with clean labels. The box set includes booklet/inserts: booklet + 11 separate pages: with age yellowing. The thin outer box has no writing, does have some age spotting and corner splitting at the top. Original John Cage holy grail in superb condition. Thanks for looking.
