Utopia, an American rock band formed in 1973 by songwriter, performer, and producer Todd Rundgren, started with a progressive rock sound and a fluid personnel list. In the late 70s, the band morphed into a tight power pop format with a stable quartet of players. Its only top-40 hit was 1980’s “Set Me Free,” written and sung by bassist Kasim Sulton (who later became known for his work with Meatloaf, Hall & Oates, and Joan Jett as well as his own solo releases).
A whole-tone modulation hits towards the end of the track (2:36), which just might be the bounciest song ever written about a doomed relationship (in this case, reportedly, between Sulton and his record company).
