One of the most commercially successful funk groups of the '70s, the multi-racial Rufus are today best remembered for launching the career of soul diva Chaka Khan, whose fiery lead vocals were easily the band's focal point. Powered by Khan -- who was eventually billed in addition to the group -- and an unerring sense of groove, Rufus scored an impressive string of hit singles on both the pop and R&B charts, which lasted through the '70s and up to Khan's official departure in 1983. Rufus grew out of the Chicago band the American Breed, which had a hit in 1968 with the oldies-radio staple "Bend Me, Shape Me." Guitarist Al Ciner, bassist Chuck Colbert, drummer Lee Graziano, and keyboardist Kevin Murphy had all played in the band at one time or another before forming a new group, originally called Smoke, with vocalists Paulette McWilliams and James Stella. Stella was quickly replaced by lead vocalist/songwriter/keyboardist Ron Stockert, and Colbert by bassist Dennis Belfield; the group changed its name to Ask Rufus, which was later shortened to Rufus. In 1972, drummer Andre Fischer -- another former American Breed member -- replaced Graziano, and a young female vocalist named Chaka Khan (born Yvette Marie Stevens) replaced McWilliams. Although Khan's dynamic stage presence helped this version of the band take off, Stockert was still the guiding force when they signed with ABC in 1973, and he lent a more pop/rock flavor to the group's self-titled debut, released later that year. Although the album sold poorly, Rufus gained a fan in Stevie Wonder thanks to their cover of his "Maybe Your Baby." Wonder gave them a new composition, the slowly grinding "Tell Me Something Good," that he'd written specifically with Khan's vocal style in mind. Pulled as a single from their second album, 1974's Rags to Rufus, "Tell Me Something Good" was a Top Five smash that turned Khan into a star; she also co-wrote the R&B chart-topping follow-up, "You Got the Love." Clearly, the band had found its niche, and a number of personnel shifts ensued: Stockert left, Belfield was replaced by Bobby Watson, and Ciner was replaced by Tony Maiden. Their funk sensibility thus bolstered, Rufus returned with a strong new album before year's end, Rufusized, which spawned two more hits in "Once You Get Started" and "Please Pardon Me (You Remind Me of a Friend)." The billing on 1975's Rufus Featuring Chaka Khan made the singer's star power official, and produced one of the group's biggest hits in the R&B number one "Sweet Thing." Dave "Hawk" Wolinski joined as a second keyboardist for 1977's mellower Ask Rufus (the hit was "At Midnight (My Love Will Lift You Up)"), and William "Moon" Calhoun replaced drummer Fischer on 1978's Street Player. Following the release of Street Player, Khan made what was perhaps an inevitable move into solo recording with the release of her debut, Chaka; despite scoring a significant hit with "I'm Every Woman," she remained an official member of Rufus. Still, the band's next album, Numbers, was recorded without her, and upon its release in 1979, it stiffed. Khan was back on board later that year for Masterjam, produced by Quincy Jones, and the band (featuring new drummer John "J.R." Robinson) was back on top of the R&B charts with "Do You Love What You Feel." However, Khan split again for 1980's Party 'Til You're Broke, and although she returned for 1981's Camouflage, Rufus' chart fortunes were slipping away. The George Duke-produced, Khan-less Seal in Red bombed, but Khan returned for one last go-round on 1983's Stompin' at the Savoy, a double-record set featuring three sides of live material and one side of new studio recordings. One of those new songs, "Ain't Nobody," became Rufus' final number one R&B hit, and also won a Grammy, allowing the group to end its career on a high note. Her contract up, Khan finally left for good afterwards and became a superstar thanks to a cover of Prince's "I Feel for You." ~ Steve Huey
