Michael S. Horwood's more than seventy compositions constitute a kaleidoscope of the traditional and the avant-garde, spanning a wide variety of contemporary idioms including twelve-tone, theatre pieces, electroacoustic (both live and pre-recorded), jazz, minimalism and neo-romanticism.

The music on this CD is clearly identified with birds but none of the pieces aim at imitation, except in passing.

"Expertly performed by the Toronto Percussion Quartet...as well as a few extra players on the larger works,...the sound quality sparkles and reveals every nuance of music that evolves from early influences by the 1960s avant-garde to a more refined style in Michael Horwood's later compositions."
