Many groups that were popular during the disco period subsequently struggled to maintain their success—even those that tried to adapt to evolving musical tastes. The Bee Gees, for instance, had only one top-10 entry (1989's "One") and three more top-40 songs (despite recording and releasing far more than that and completely abandoning disco in their 1980s and 1990s songs) in the United States after the 1970s, even though numerous songs they wrote and had "other" artists perform were successful. Of the handful of groups "not" taken down by disco's fall from favor, Kool and the Gang, Donna Summer, the Jacksons—and Michael Jackson in particular—stand out: In spite of having helped "define" the disco sound early on, they continued to make popular and danceable, if more refined, songs for yet another generation of music fans in the 1980s and beyond. Earth, Wind & Fire also survived the anti-disco trend and continued to produce successful singles at roughly the same pace for several more years, in addition to an even longer string of R&B chart hits that lasted into the 1990s.
