In early 1975, Yes was riding high on the wave of success following the release of their groundbreaking album "Relayer." This record, dropped just a month earlier, was notable for its intricate compositions and the introduction of keyboardist Patrick Moraz. His presence brought a fresh dynamic to the band's sound, which was on full display during their electrifying performance at Loftus Road Stadium in London. It’s interesting to note that "Relayer" includes the epic piece "The Gates of Delirium," a complex suite that showcases the band's signature progressive rock style. This concert, part of the Relayer tour, not only highlighted the band's virtuosic musicianship but also marked a period when they were at the forefront of the progressive rock movement. Just a year after this concert, Moraz would hand over the keys back to Rick Wakeman, making this a pivotal moment in the band's ever-evolving lineup. So, when you hear this live recording, remember it’s a slice of Yes history with a real sense of transition.
