In August 1978, when Yes took the stage at the Boston Garden for their "Heart of the Sunrise" performance, they were riding high off the wave of their 1977 album, "Going for the One." This album marked a significant moment for the band, as it was their first released after the departure of keyboardist Patrick Moraz, leading to a fresh sound and renewed energy within the group. Notably, "Going for the One" featured a return to the more classic symphonic style while still incorporating a sense of wanderlust that characterized their earlier work. It’s fascinating to think about how live performances, like the one captured in this video, allowed fans to experience the band’s evolving artistry right before their eyes. The synergy of the band members during this period—especially the seamless interplay between Jon Anderson’s ethereal vocals and Chris Squire’s distinctive bass—made concerts an exhilarating affair. Fans couldn't get enough, and that palpable excitement in the air continues to resonate through their live recordings today.
