The New York punk band Blondie, with Deborah Harry as lead singer, was quite a force in the late Seventies. Their fourth album, 1979’s Eat to the Beat, was the first album ever to be simultaneously released as a track-by-track video LP – only a few years after the first consumer VCRs were released in the U.S., and two years before the launch of MTV. But before Eat to the Beat, there was Parallel Lines, the 1978 album that included “One Way or Another” and “Heart of Glass.” This documentary revisits the making of that album, and the New York of that era, and interviews not only the Blondie band members and record producer, but former NY Mayor Ed Koch.
