The band has been led by two different frontmen who never played together in the band at the same time. From 1974 until 1979, John Foxx was frontman and main driving force behind Ultravox. Foxx left the band to embark on a solo career. Following Foxx's departure, with the three remaining members in hiatus, Midge Ure took over as lead singer, guitarist, and frontman. Ure revitalised the band and drove it to commercial success lasting until the mid-1980s. Ure left the band in 1987 after establishing a solo career and the group disbanded for a while. A new line-up, led by sole original band member keyboard player/violinist Billy Currie, was formed in 1992, but achieved little success.
