Utopia was an American rock band formed in 1973 by Todd Rundgren. During its first three years, the group was a progressive rock band with a somewhat fluid membership known as Todd Rundgren's Utopia. Most of the members in this early incarnation also played on Rundgren's solo albums of the period up to 1975. By 1976, the group was known simply as Utopia and featured a stable quartet of Rundgren, Kasim Sulton, Roger Powell and John "Willie" Wilcox. This version of the group gradually abandoned progressive rock for more straightforward rock and pop.

Todd Harry Rundgren is an American musician, singer, songwriter, and record producer who has performed a diverse range of styles as a solo artist and as a member of the bands Nazz and Utopia. He is known for his sophisticated and often unorthodox music, his occasionally lavish stage shows, and his later experiments with interactive art. He also produced music videos and was an early adopter and promoter of various computer technologies, such as using the Internet as a means of music distribution in the late 1990s.
