Polyrock was an American post-punk/new wave band formed in New York City in 1978 and active until the mid-1980s. Strongly influenced by minimalism, the group was produced by the composer Philip Glass and Kurt Munkacsi. The band, led by singer/guitarist Billy Robertson (formerly of the group Model Citizen), had a keyboard-heavy, pattern-based sound strongly reminiscent of Glass’s work; in fact, Glass performed on their first two albums. Polyrock’s lineup also included vocalist Catherine Oblasney, guitarist Tommy Robertson, drummer Joseph Yannece, keyboard player Lenny Aaron, and Curt Cosentino. The group signed with RCA by 1980, and delivered their debut album that same year. Another album followed in 1981 (Changing Hearts), but Polyrock disbanded in 1982. The band are sometimes said to have released another album in 1981 (Electro-Romantic), but, apparently, no such album exists. They were often compared by critics to Talking Heads, another band of the same era, though they never approached that band’s fame.
