"Suarogate" is a work of some '70s minutes' duration for vocal quartet, flute, trumpet, trombone, steel strings, percussion instruments (three players) and sirens. "Whether produced by nature or by human beings, logs or metal containers, Staub turned these objects into his 'acoustical material' in the original sense of the word. He was, in a manner of speaking, constantly en route on a voyage of discovery of sounds. At first, he built his own instruments and the result is marked by a close proximity to arte provera, a rejection of overblown techniques, and an almost ecological renunciation of compositional devices. The second stage is the compositional process per se, e.g. the gradual incorporation of traditional instruments in his wholly original 'sound concretisations'. Volker Staub's composition is formed of 23 (partially interpenetrating) pieces which form new entities at a higher level of organisation."
