Piano 85 (for piano and electronics) (1962) Dedicated to Moriyasu Harumi and composed in Osaka. This last piece in the series is different from the others: it is to be performed on its own, and live electronics are to be used. Glissandi are used and feedback instructions are given in the score. The complete set of pieces, including several versions for multiple pianos, was recorded by pianist Steffen Schleiermacher for Musikproduktion Dabringhaus Und Grimm and released in a 2-CD set in 1998. The set includes "Electronic Music For Piano" in a version for two pianos. Another complete set of the pieces was issued in 2012 by Brilliant Classics, performed by Giancarlo Simonacci. This set does not include versions for multiple pianos, or the "Electronic Music For Piano". Editions Edition Peters 6729-36. (c) 1960 by Henmar Press.
