Europe pioneered Musique Concrete and Electronic Music in radio Studios, while in the USA it was tape music in Universities. The pioneer at Columbia-Princeton (1952) was Ussachevsky. Here at last collected are some of these pieces (earliest 1957 so not the oldest, but the oldest are very clunky), the 1960's electronicised choir piece "Three Scenes from the Creation" and the later "Missa Brevis". The first six tracks are historic and indispensable for any student of the form, as well as being fine pieces.
