“There is absolutely nothing wrong with the original 1971 studio recording of Yes’s Perpetual Change. It just doesn’t go as far as strong as gobsmackingly wow!!! as the 1972 live recording that showed up on the triple live set Yessongs. Because they really do set the atmosphere on fire here, one of the last tracks ever recorded with drummer Bill Bruford, so yeah, the classic Yes lineup (my version of it anyway), which does need to be raved about if only for that point maybe halfway through Perpetual Change where the band are effectively playing two completely different songs at the same insane time, and it works, finally blowing off into a feedback overload that quickly segues into a Jon Anderson vocal harmony, and then BAM!!! into an extended outro, the tightest band on the planet at the time (seriously, even Led Zeppelin had to be looking over their shoulders in 1972) bouncing back and forth from improvised bits to insanely abrupt changes, on and on, higher and deeper until the only real flaw, which is the overextended drum solo (not bad, just not necessary). As a musician friend once put it, Perpetual Change is the secret to everything that was great about Yes, because they were perpetual change (up until around 1975 anyway), not just evolving from album to album, but within the songs themselves. Everything was possible and they had the smarts (and the chops) to make it so.” (Philip Random)
