@kza thanks! the piece is built on 6 ‘freeze modules’ freezing the first 6 notes the soprano sings. from there, these frozen pitches start to shift one by one, forming a continously changing bed of harmony on which the singer is improvising (with somewhat of a score). other electronic layers were done with some m4l devices I created some time ago (ReversR, GlitchR, Microlooper, …).
The piece sat in the middle of the show which was called ‘Extremely Loud’ … it was a welcome change from the glitch/heavy metal/techno stuff surrounding it 
here’s a first sketch of the freezer I did for the piece (for 128 vari-bright grid; it’s quite heavy on the CPU so increase vector size if necessary).
