Few bands embody progressive rock’s ambition and inventiveness like Yes. Formed in London in 1968, the group forged a dazzling blend of symphonic textures, virtuosic playing and soaring harmonies that defined prog rock in the 1970s. They achieved four consecutive US Platinum albums beginning with The Yes Album (1971) and set new standards for complexity and grandeur, while singles such as ‘Roundabout’ and ‘Owner of a Lonely Heart’ brought them mainstream success. Over the decades, Yes have remained one of the most successful, influential and longest-lasting prog rock bands, winning Grammy awards and being inducted into the Rock and Roll Hall of Fame in April 2017.By the end of the 1980s, Yes had splintered into two parallel camps: the line-up led by Jon Anderson, Bill Bruford, Rick Wakeman and Steve Howe, and the version featuring Chris Squire, Trevor Rabin, Tony Kaye and Alan White. In an unprecedented move, these factions united in 1991 for the aptly titled Union album. Though recorded in separate sessions across continents with a variety of producers, Union brought together eight of the band’s most celebrated members on a single record – a milestone in Yes history and a springboard for an equally ambitious tour.The ‘Union Tour’ ran from 9 April 1991 to 5 March 1992, covering North America, Europe and Japan. It was the first and only time the full octet – Anderson, Squire, Rabin, Kaye, Bruford, Wakeman, White and Howe – performed together on stage. Playing on a central revolving stage (a spectacular staging concept they had first pioneered in 1978), the band delivered a career-spanning setlist that fused the fire of their 1970s epics with the polished power of their 1980s hits. For many fans, it was the ultimate Yes experience: eight legends sharing one stage, in one unforgettable moment.
