Recording of Will Eisma's "Le grand silence d'un seul oiseau" ("The great silence of a single bird") for tape. During World War II, a network of 40,000 km of trenches crossed South Flanders and the North of France. Still today, there remains part of these trenches as a long underground tunnel somewhere around Metz and Verdun. The composition represents an imaginary underground journey from Calais to the Swiss border, through the infernal moles, in the gloomy and frightening obscurity of this absurd war. The poem of Ab Van Eyk tells of these horrors: "Someone walks forward, slowly spitting out his lungs, while a bird pass near me, the gas ......... The night shows fiery angels, among the lights of the "no man's land "; until the twilight silence arrives, the great silence of a only bird, just before sunrise raspberry color." The piece was composed and realized in the studio Five Roses in April 1981.

Recording of Jacqueline Ozanne's "Son recif" for voice and tape. This piece comes from a work on the myth of the sirens and includes texts written on this theme in their original languages. As the singer/speaker repeats the story, it is crossed by the sounds of these languages, by songs that cannot continue, as well as successive states of emotion. The electroacoustic tape plays a constant dramatic role: sometimes worrisome, sometimes reassuring, sometimes enveloping presences, it continually influences the interpreter in their vocal and dramatic production. The performance includes a video projection.

Recording of Bogusław Schäffer's Maa'ts for tape (4-lane). The composition if a collage for voices and electronics. The choir sings in harmonically exact microcompositions.The piece was produced in February 1981 in the studio of the Technical University Berlin.
