Genre: R&B
Rufus was an American funk band from Chicago, Illinois best known for launching the career of lead singer Chaka Khan. They had several hits throughout their career, including "Tell Me Something Good", "Sweet Thing", and "Ain't Nobody".
In 1968, The American Breed (Gary Loizzo, Al Ciner, Charles (Chuck) Colbert and Lee Graziano) had a top ten hit with the classic rock single, "Bend Me, Shape Me,". After much success, Colbert and Graziano (without Loizzo who pursued a successful production career) created a new group, adding later day "Breed" members Kevin Murphy on (keyboards) and Paulette McWilliams (vocals), plus James Stella (vocals) and Vern Pilder (guitar) from the bar band "Circus". They re-emerged in 1969 under the name "Smoke".
