Bruce Eder claims that "the rot" in progressive rock "started to set in during 1976, the year Emerson, Lake & Palmer (ELP) released their live album Welcome Back My Friends". Eder claims that this album was "suffering from poor sound and uninspired playing" which "stretched the devotion of fans and critics even thinner." He claims that "the end [of progressive rock] came quickly: by 1977, the new generation of listeners was even more interested in a good time than the audiences of the early 1970s, and they had no patience for 30 minute prog-rock suites or concept albums based on Tolkien-esque stories." He asserts that by the late 1970s and early 1980s, "ELP was barely functioning as a unit, and not producing music with any energy; Genesis was redefining themselves ... as a pop-rock band; and Yes was back to doing songs running four minutes ... and even releasing singles."

In 1974, four of progressive rock's biggest bands – Yes, Emerson, Lake & Palmer, Genesis and King Crimson – all went on indefinite hiatus or experienced personnel changes. Members of Yes and ELP left to pursue solo work, as did Genesis lead singer Peter Gabriel, who left his band (though Genesis would continue with Phil Collins as lead vocalist), and Robert Fripp announced the end of King Crimson after the release of their Red

which was more of a straight ahead rock album in contrast with the group's previous efforts and even gave them more commercial success than before. When, in 1977, Yes and ELP reformed, they had some success, but were unable to capture their previous dominance.

The 1975 and 1976 period saw progressive rock bands using more and more elaborate stage shows, thus moving away from its original "music first" ethos.
