Utopia is an American rock band. In its initial incarnation, in 1973-75, the group was a progressive rock band with a fluid membership known as "Todd Rundgren's Utopia". By 1976, the group was known simply as Utopia and was a stable quartet of Rundgren, Kasim Sulton, Roger Powell and John "Willie" Wilcox. This incarnation of the group gradually abandoned prog-rock for straight rock, new wave and power pop, and scored the top 40 hit "Set Me Free" in 1980. Though often thought of as a Rundgren-oriented project, all four members of Utopia wrote, sang, produced and performed on their albums; "Set Me Free", for example, was sung by Sulton.
Utopia broke up in 1986, but reunited briefly in 1992. More recently, beginning in 2011 the earlier prog-rock incarnation known as Todd Rundgren's Utopia was revived for a series of live shows.
