*2022 Stock.* This CD contains 3 X Refrain 2000 for piano with 3 wood blocks (Benjamin Kobler), sampler-celesta with 3 antique cymbals (Antonio Pérez Abellán), and vibraphone with 3 cow bells and glockenspiel (Andreas Boettger). This is essentially 3 "versions" of Refrain (originally composed in 1959, and recorded earlier on the Stockhausen Edition no. 6) with the indeterminate notation strip in 3 different orientations and with some minor additions to the coda. In a concert performance, all 3 versions are supposed to be performed in sequence as heard on the CD, separated by verbal introductions.
