An adaptation of the chamber orchestra work Stream 3, this version assigns most of the orchestral parts to an electronically realized backing track, and leaves the foreground to a combo comprising percussion, electric guitar, piano, double bass and drum kit. There is a considerable degree of flexibilty in options for performing the work - alternative tape parts are provided so that the other live instrumental combinations may be used such as percussion only, percussion and guitar, percussion, guitar and bass, and percussion, guitar, bass and piano.
