Early electronic music from 1959 to 1969 produced by the Institute of Sonology/Instituut voor sonologie, in Utrecht, Holland. Works composed by Dick Raaijmakers, Frits Weiland, Ton Bruynel, Konrad Boehmer, Gottfried Michael Koenig, and Rainer Riehn. Raw material -- a real revolution: music produced by machines designed to construct a new era. Officially founded on September 1, 1960, at the instigation of several people representing cultural institutions, the Institute for Sonology had already taken initiatives in the field of electroacoustic music since 1954. A large complex of studios (initially under the name STEM = STudio voor Electronische Muziek) was set up under the patronage of Utrecht University in an old house on Plompetorengracht in Utrecht. Instruments, machines, and tapes (among them, that of Varèse's Electronic Poem") coming from Philips laboratories. Double-LP includes insert." - Sub Rosa.
