Composer Mauricio Kagel, Imp of the Avant-Garde, Dead at 76

“His pieces include a string quartet to be played by gloved musicians using knitting needles (String Quartet II); a lecture on avant-garde music that is interrupted by music and mime (Sur scène); and an orchestral piece in which the conductor tries to get through a performance while negotiating with hostage-takers (Kidnapping in the Concert Hall).”
