As members of Yes, Anderson and Wakeman not only helped shape the British band’s unique sound, but also influenced the entire progressive rock genre. As any fan can tell you, Anderson and bassist Chris Squire founded Yes in 1968, but it was Wakeman joining the group for its fourth album, 1971’s Fragile, that further defined the band. Replacing original keyboardist Tony Kaye, Wakeman brought then state-of-the-art instruments such as the Mellotron and the Minimoog synthesizer to Yes, resulting in a fuller, more orchestral sound.

But Wakeman’s relationship with Yes was an often on-again, off-again affair with the keyboardist leaving the group in 1974, returning in 1976 for the Going For The One sessions and splitting again in 1980. These days Geoff Downes, who replaced Wakeman in 1980, is playing keyboards for Yes, while Canadian singer Benoit David stands center stage belting out the songs Anderson made famous.
