White founded Earth, Wind & Fire in Chicago in 1969. He had previously honed his chops as a session drummer for Chess Records, where he played on songs by the likes of Fontella Bass, Billy Stewart, and Etta James, among others. In 1967, he'd replaced Redd Holt in the popular jazz group the Ramsey Lewis Trio, where he was introduced to the kalimba, an African thumb piano he would use extensively in future projects. In 1969, he left Lewis' group to form a songwriting partnership with keyboardist Don Whitehead and singer Wade Flemons. This quickly evolved into a band dubbed the Salty Peppers, which signed with Capitol and scored a regional hit with "La La Time." When a follow-up flopped, White decided to move to Los Angeles, and took most of the band with him; he also renamed them Earth, Wind & Fire, after the three elements in his astrological charts. By the time White convinced his brother, bassist Verdine White, to join him on the West Coast in 1970, the lineup consisted of Whitehead, Flemons, female singer Sherry Scott, guitarist Michael Beal, tenor saxophonist Chet Washington, trombonist Alex Thomas, and percussionist Yackov Ben Israel. This aggregate signed a new deal with Warner Bros. and issued its self-titled debut album in late 1970. Many critics found it intriguing and ambitious, much like the 1971 follow-up, The Need of Love, but neither attracted much commercial attention, despite a growing following on college campuses and a high-profile gig performing the soundtrack to Melvin Van Peebles' groundbreaking black independent film Sweet Sweetback's Baadasssss Song.

Dissatisfied with the results, White dismantled the first version of EWF in 1972, retaining only brother Verdine. He built a new lineup with female vocalist Jessica Cleaves, flute/sax player Ronnie Laws, guitarist Roland Bautista, keyboardist Larry Dunn, and percussionist Ralph Johnson; the most important new addition, however, was singer Philip Bailey, recruited from a Denver R&B band called Friends & Love. After seeing the group open for John Sebastian in New York, Clive Davis signed them to CBS, where they debuted in 1972 with Last Days and Time. Further personnel changes ensued; Laws and Bautista were gone by year's end, replaced by reedman Andrew Woolfolk and guitarists Al McKay and Johnny Graham. It was then that EWF truly began to hit their stride. 1973's Head to the Sky (Cleaves' last album with the group) significantly broadened their cult following, and the 1974 follow-up, Open Our Eyes, was their first genuine hit. It marked their first collaboration with producer, arranger, and sometime songwriting collaborator Charles Stepney, who helped streamline their sound for wider acceptance; it also featured another White brother, Fred, brought in as a second drummer. The single "Mighty Mighty" became EWF's first Top Ten hit on the R&B charts, although pop radio shied away from its black-pride subtext, and the minor hit "Kalimba Story" brought Maurice White's infatuation with African sounds to the airwaves. Open Our Eyes went gold, setting the stage for the band's blockbuster breakthrough.

In 1975, EWF completed work on another movie soundtrack, this time to a music-biz drama called That's the Way of the World. Not optimistic about the film's commercial prospects, the group rushed out their soundtrack album of the same name (unlike Sweet Sweetback, they composed all the music themselves) in advance. The film flopped, but the album took off; its lead single, the love-and-encouragement anthem "Shining Star," shot to the top of both the R&B and pop charts, making Earth, Wind & Fire mainstream stars; it later won a Grammy for Best R&B Vocal Performance by a Group. The album also hit number one on both the pop and R&B charts, and went double platinum; its title track went Top Five on the R&B side, and it also contained Bailey's signature ballad in the album cut "Reasons." White used the new income to develop EWF's live show into a lavish, effects-filled extravaganza, which eventually grew to include stunts designed by magician Doug Henning. The band was also augmented by a regular horn section, the Phoenix Horns, headed by saxophonist Don Myrick. Their emerging concert experience was chronicled later that year on the double-LP set Gratitude, which became their second straight number one album and featured one side of new studio tracks. Of those, "Sing a Song" reached the pop Top Ten and the R&B Top Five, and the ballad "Can't Hide Love" and the title track were also successful.

Sadly, during the 1976 sessions for EWF's next studio album, Spirit, Charles Stepney died suddenly of a heart attack. Maurice White took over the arranging chores, but the Stepney-produced "Getaway" managed to top the R&B charts posthumously. Spirit naturally performed well on the charts, topping out at number two. In the meantime, White was taking a hand in producing other acts; in addition to working with his old boss Ramsey Lewis, he helped kickstart the careers of the Emotions and Deniece Williams. 1977's All n' All was another strong effort that charted at number three and spawned the R&B smashes "Fantasy" and the chart-topping "Serpentine Fire"; meanwhile, the Emotions topped the pop charts with the White-helmed smash "Best of My Love." The following year, White founded his own label, ARC, and EWF appeared in the mostly disastrous film version of Sgt. Pepper's Lonely Hearts Club Band, turning in a fine cover of the Beatles' "Got to Get You Into My Life" that became their first Top Ten pop hit since "Sing a Song." Released before year's end, The Best of Earth, Wind & Fire, Vol. 1 produced another Top Ten hit (and R&B number one) in the newly recorded "September."

1979's I Am contained EWF's most explicit nod to disco, a smash collaboration with the Emotions called "Boogie Wonderland" that climbed into the Top Ten. The ballad "After the Love Has Gone" did even better, falling one spot short of the top. Although I Am became EWF's sixth straight multi-platinum album, there were signs that the group's explosion of creativity over the past few years was beginning to wane. 1980's Faces broke that string, after which guitarist McKay departed. While 1981's Raise brought them a Top Five hit and R&B chart-topper in "Let's Groove," an overall decline in consistency was becoming apparent. By the time EWF issued its next album, 1983's Powerlight, ARC had folded, and the Phoenix Horns had been cut loose to save money. After the lackluster Electric Universe appeared at the end of the year, White disbanded the group to simply take a break. In the meantime, Verdine White became a producer and video director, while Philip Bailey embarked on a solo career and scored a pop smash with the Phil Collins duet "Easy Lover." Collins also made frequent use of the Phoenix Horns on his '80s records, both solo and with Genesis.

Bailey reunited with the White brothers, plus Andrew Woolfolk, Ralph Johnson, and new guitarist Sheldon Reynolds, in 1987 for the album Touch the World. It was surprisingly successful, producing two R&B smashes in "Thinking of You" and the number one "System of Survival." Released in 1990, Heritage was a forced attempt to contemporize the group's sound, with guest appearances from Sly Stone and MC Hammer; its failure led to the end of the group's relationship with Columbia. They returned on Reprise with the more traditional-sounding Millennium in 1993, but were dropped when the record failed to recapture their commercial standing despite a Grammy nomination for "Sunday Morning"; tragedy struck that year when onetime horn leader Don Myrick was murdered in Los Angeles. Bailey and the White brothers returned once again in 1997 on the small Pyramid label with In the Name of Love.

After 2003's The Promise, a mix of new material and fresh looks at classics, the group realigned with several top-shelf adult contemporary artists and released 2005's Illumination, which featured a much-publicized collaboration with smooth jazz juggernaut Kenny G. Earth, Wind & Fire continued to tour and made a show-opening appearance on American Idol's "Idol Gives Back" show in 2007. Three years later, Maurice and Verdine White, Bailey, Dunn, and McKay were inducted into the Songwriters Hall of Fame.
