Three warm, beautiful, and gently humorous compositions for computer-aided and improvising musicians (violin), (mutantrumpet), and (trumpet). (1984) is a lovely piece originally commissioned by the Cunningham Dance Company. In two scenes for performer and computer, the work features composer/performer on electric violin improvising -like melodies amidst lovely sustained chords, ascending and arpeggiated filter sweeps, and electronic pops ("like champagne corks"). The feeling of this music is direct, with a charming and engaging simplicity. (1990) is a rich and intriguing two-part soundscape created after worked in 's Kreuzberg studio. The first section features a rhythmic mix of arpeggiated string-like figures that rapidly alternate and cascade, electronic bell and toy piano-like figures, tabla-like drums, scarcely identifiable animals that roar and caw and sing (triggering electronic events), a lightly washing seashore wave, and beautiful chords that illuminate, then fade away. This is not a collage, but a performance. The second section is similar to the first in its sound palette, with different rhythmic variations. Featuring and , (1983-1986) is divided into three scenes, beginning with an active sequence of computer chords and small percussive rhythms. The mutantrumpet (a invention with triple bells and mutable slides) is used to improvise among the computer tonalities. The chord sequences and rhythms of the second scene are in a new tuning, a unique kind of and cosmic blend. The mutantrumpet plays short single notes and melodic fragments as the sequence modulates through different tonal centers. The third scene features a slower sequence of rich modal (and still slightly " ") computer harmonies with two trumpets playing long sustained tones that grow from or anticipate subsequent chords; one of the trumpeters initiated new computer sequences with a foot pedal. ~ "Blue" Gene Tyranny
