In June 1976, when Yes took to the stage at Roosevelt Stadium for a full FM concert, they were riding high on the success of their album *Relayer*, which had dropped just the previous year. This album showcased a pivotal moment for the band, marking both an evolution in their musical complexity and a lineup shift with the arrival of keyboardist Patrick Moraz. Notably, the live performance featured a selection of tracks from *Relayer*, including the ambitious “The Gates of Delirium,” which highlights their signature mix of intricate melodies and extended instrumental passages. The atmosphere of the concert, set in a legendary venue, captured the essence of an era when progressive rock was pushing boundaries. Interestingly, this performance is among the few that feature Moraz’s distinct contributions on stage, offering fans a glimpse into the band's dynamic transformation during one of their most creatively fertile periods. It’s a reminder of how live music fosters an electric connection between artists and audiences.
