The original recording of Berio's dark vocal piece Sinfonia, and one of the pivotal moments when the Swingle Singers switched from doing jazzy versions of classical tunes to work that was more avant garde. Their high level of talent is apparent in this recording, and they give Berio's work a nice haunting sound, with a feel that's even spookier because you sort of recognize them as a pop group, but one that's gone a little crazy here. Cool stuff, and with a good set of notes. LP, Vinyl record album
