This is a collection of electronic works composed between 1959 and 1969 at the Institute for Sonology in Utrecht, Holland. Once again, Sub Rosa offers a chance to reflect upon a rare lineage of electronic music's origins, a revolution of the fifties and sixties when an art form was emerging without a base -- ex nihilo -- a new music produced by machines designed to construct the new. Utrecht University's large complex of studios that comprised the Philips laboratories housed an extensive collection of early electronic instruments and tapes. The Institute for Sonology was officially established in 1960, its founding instigated by academic and cultural initiatives in the field of electroacoustic music that had already begun years before -- among them, Edgar Varèse's construction of his famous "Poeme Electronique," presented at the Philips Pavillon at the 1958 World's Fair in Brussels. Comprised of the most basic components -- oscillators, filters, and tapes -- listening to these songs today offers rare insight into an important period in early electronic music, a cross section of primitivism and futurism. This collection features work by early Dutch electronic music pioneers Dick Raaymakers, Frits Weiland, Ton Bruynel, Konrad Boehmer, Gottfried Michael Koenig and Rainer Riehn.
