In November 1977, Yes was firmly in the midst of their creative evolution, having just released *Going for the One*. It was a significant album for the band, marking a herculean effort to blend their classic progressive rock sound with more mainstream elements, all while retaining their intricate musicality. The live rehearsal recording, *Yes - Parallels rehearsal, Going For The One Sessions*, gives us an intriguing glimpse into this transformative period. During this time, Yes was experimenting with a fresh sonic palette, and *Parallels*, one of their standout tracks, reflects this vibe beautifully. Interestingly, while recording this live rehearsal in Glasgow's iconic Apollo Theatre, the band was also embracing their burgeoning reputation as a live act renowned for epic performances – a feat that would only continue to solidify their legacy in the annals of rock history. It's fascinating how the energy in those rehearsal sessions could be felt and ultimately translates into their live performances. What better way to capture the essence of a band on the brink of a new era?
