Polyphony was a short-lived US outfit active in the early 70's. The band; consisting of Martin Ruddy (bass, vocals), Christopher Spong (drums), Craig Massey (vocals, organ, moog), Glenn Howard (vocals, guitars) and Chatty Cooper (percussion); recorded the album Without Introduction which was released in 1971. On this creation they fused vintage symphonic prog with psychedelic tendencies. It is thought that the band disbanded soon after the release of this album; which was the only one made by this act. For many years an obscurity sought after by collectors, the album has been available on CD for some time now; after a surge of interest and curiosity about this creation came at the start of the internet age.
