*2022 Stock. Includes a 100-page booklet.* Helikopter-StreichQuartett (Helicopter String Quartet, 3rd scene of Wednesday from Light) for string quartet and 4 helicopters (1992/93). The 3rd Scene from the opera Mittwoch Aus Licht (Wednesday from Light) is centered on a string quartet piece, accompanied by the sounds of close-miked helicopter rotor engines, and interrupted throughout by shouted numbers in German (by the string quartet players). In a staged concert, members of the string quartet are flown around the performance hall in 4 separate helicopters. This aspect is left up to the imagination for the CD, although there is a DVD documentary on the project available elsewhere. Prior to and following the piece/flight are "press conferences" which are actually part of the opera scene direction. These are not scripted and have different moderators for different performances (on this Stockhausen Edition, he moderates the premiere performance himself in English).

The Arditti String Quartet are featured in both the live premiere recording and a studio recording on the 2nd CD. The music itself is based on a polyphonic web of string tremolo figures, gliding up and down to form melodic contours, with the shouted numbers corresponding to the Licht "Lucifer" formula.
