Billy has started using a new musical format known as “Musique Concrète”. Musique Concrète is an Electronic/Acoustic music that is made with both electronic and acoustic sounds derived from different media; synthesizers, instruments, samples, voices etc. Compositions are not restricted to any standard rule of music. This compositional practice was first developed by Pierre Schaeffer in the early 1940s.
