SCHAEFFER, P. / STOCKHAUSEN, K. / BOULEZ, P. … Le Groupe de Recherches Musicales (The Group of Musical Research) of the O.R.T.F. (Office of the French Radio-Television) is known in the world principally as the promoter of an original technique of realization as well as reflection : Musique concr?te. For more than fifteen years, the Groupe de Recherches Musicales has thus founded its experience, its methods of research and particular techniques upon a confrontation between the musical act, reflection upon its elements, experimentation on sound sources, and the electroacoustical means. Grouped around Pierre Schaeffer and Francois Bayle, composers and researchers try to give new direction to musical activity through the conjugated action of a program of Fundamental Research on the languages of music (concrete, electronic, but also instrumental and oriental) and a program of Expression, resulting in original compositions as well as essays for the ballet, theater, cinema, or television (...) In this LP you can find some great examples of the incredible production of many of the most celebrated composers of the Movement': Boulez, Stockhausen, Parmegiani among others
