Paul Zukofsky to Morton Feldman used as liner notes in the CD release of his recording ‘For John Cage’: I can tell you that when playing your recent music I feel very close to those rug-makers working away — first the border, the same stitch so many times, now a different strand, fewer times, now we start a pattern, it’s finished, a background, etc. Certainly the feeling is very different from that of other music, where I walk from room to room, each one with certain proportions, order, and progression. Also — the rug-making explanation helps account for the tiny variations you play within timing and intonation — the equivalent of the irregularities in a hand-sewn rug.
