One of the biggest disco hits of all time, "Boogie Wonderland" took Earth, Wind & Fire to the Top Ten on both the pop and R&B charts in 1979. One of the few records that paired two full-fledged groups successfully, the combination of EWF and the Emotions worked wonders here and it remains a classic of the period. A virtual call to arms of the disco scene, the lyrics relate the power of the extinct musical form, and although loaded with clichés, it still retains a certain period charm. The fantasy life of disco patrons is celebrated here, and in this way, it was a sort of theme song to the Studio 54 crowd. Musically, it's a straight four-on-the-floor rhythm with a funk melody, and despite its simplicity -- or because of it -- it was a huge and accessible record that is still played regularly on oldies R&B radio and is available on Sony/Legacy's The Essential Earth, Wind & Fire.
