Yes are an English progressive rock band formed in London in 1968, generally regarded as one of the archetypal bands and pioneers of the genre. Despite many lineup changes, occasional splits within the group, and the ever-changing trends in popular music, the band have continued for more than 40 years and still retain a large following. They have sold over 30 million albums. The band's music blends symphonic and other "classical" structures with their own brand of rock music.
Although the band's sole consistent member has been bass player Chris Squire, Yes are also generally noted for the distinctive high-register vocals of former lead singer Jon Anderson and the eclectic musical stylings of a succession of guitarists (Steve Howe, Peter Banks, Trevor Rabin, Billy Sherwood), keyboard players (Rick Wakeman, Tony Kaye, Patrick Moraz, Geoff Downes, Igor Khoroshev, Oliver Wakeman), and drummers (Alan White and Bill Bruford). Several band members became celebrated musicians and/or bandleaders in their own right, and a 1980 lineup of the band was briefly fronted by Trevor Horn (shortly before he became one of rock music's most celebrated record producers). The band's current lineup are Squire, Howe, White, Oliver Wakeman (keyboards) and Benoît David (lead vocals).
