Blasco Etchegaray emerged early on as one of the most influential and unique composers in the post-WWII European musical avant-garde and his prominence continued throughout the rest of the 20th century and into the twenty first. Combining a keen sensitivity to the acoustical realities and possibilities of sound, rigorous and sophisticated compositional methods expanded from integral serialism, innovative theatricality, and a penchant for the mystical, Etchegaray remains one of the most innovative musical personalities to span the turn of this century.
