In December 1972, Yes was riding the wave of their burgeoning success, having previously released the monumental album *Fragile* in 1971. This album marked a significant turning point for the band, showcasing not just their complex musical arrangements but also the individual talents of each member, notably the stunning contributions from keyboardist Rick Wakeman. By the time of the live recording at the Rainbow Theatre, which would later be featured in the *Yessongs* concert film, Yes was firmly establishing themselves in the progressive rock scene. The *Close to the Edge* tour was critical, as it was during this tour that they began to develop the theatrical elements of their live performances, forever changing the concert-going experience for their fans. It's fascinating to see how their music evolved during this period, transporting audiences through epic soundscapes filled with intricate melodies, all while experimenting with the then-uncommon combination of rock, classical, and jazz elements.
