This is the fourth Henri Pousseur CD in Sub Rosa's Early Electronics series, exploring the work of this Belgian theoretician and experimental/avant garde composer. Along with previous releases in this series, Musique Mixte will cover all his electronic music and his most radical works between 1953 and 1988 -- 35 years of research and experiments. These recordings are a continuation of Sub Rosa's earlier releases, namely: Liège à Paris (a piece composed thanks to Luciano Berio and premiered at the grand opening of the Centre Georges Pompidou in Paris, in 1977), the 8 Études Paraboliques box set (over 220 minutes of music realised in Cologne, 1972, at the WDR's studios -- the last étude featuring Stockhausen's participation) and 4 Parabolic Mixes, (four takes on the work by Henri Pousseur himself, Robert Hampson, Philip Jeck and Markus Popp). The two pieces featured on Musique Mixte (voice, pianos, various electroacoustic devices) are magnum opuses in Pousseur's body of work, though they are seldom heard -- "Jeu de Miroirs de Votre Faust" has been unavailable for a long time, while "Crosses of Crossed Colors" is released here for the first time ever.
