Exploring 20th century repertoire - both well-loved masterpieces and new discoveries - this 14-CD anthology reflects the diverse aesthetic strands of Pierre Boulez's programming over the course of his ground-breaking and influential career. These Erato recordings, made between 1966 and 1992, feature composers otherwise absent from Boulez'sdiscography - Xenakis, Donatoni, Grisey, Dufourt, Ferneyhough, Harvey and H�ller - and the first CD release of the interpretation of Stravinsky's incantatory Les Soucoupes in the version for female voices and four horns.
