Kool and The Gang's story starts in the Jersey City projects. They were teenagers, studying Miles Davis albums and James Brown singles, jamming in basements, partying for the people in a swirl of Black consciousness. In 1969 they made their first record. Still teenagers, and full of confidence, Kool and The Gang named that first record after themselves. Their confidence and creativity produced a string of loose-but-tight, "fun" records, culminating in the Pop Chart smash Jungle Boogie . Kool & The Gang didn't need a singer then: the horns were the lead voice; the fans chanted along. Their songs were featured in films like Rocky and Saturday Night Fever

In 1964 Robert Bell (b.1950), his brother Ronald and five high school friends organized an instrumental band called the Jazziacs . Along with the Bell brothers, the band still includes original members Dennis "D. T." Thomas (alto saxophone), Charles Smith (guitar), Clifford Adams (trombone), Robert Mickens (trumpet) and George Brown (drums). They were cooperating occasionally with jazz musicians McCoy Tyner, Pharoah Sanders and Leon Thomas. Kool and The Gang's first album, Kool & The Gang, on the De- Lite label in 1970, but the group didn't reach popular success until the 1973 release of Wild and Peaceful, which contained the hit gold singles, "Funky Stuff", "Jungle Boogie" and "Hollywood Swinging". In 1976 Kool and The Gang received Grammy Award for "Open Sesame" from "Saturday Night Fever" soundtrack.

A new lead singer J. T. Taylor joined Kool and The Gang who was an amateur nightclub singer from New Jersey. Taylor was also no stranger to Kool & The Gang's music. They released the album Ladies' Night. Taylor's creamy voice gave the album popularity, the singles "Too Hot" and "Ladies' Night" reaching gold and platinum status. Besides the inclusion of a new lead singer, the group's change to a pop sound was raised by producer Eumir Deodato , who, starting with Ladies' Night, produced the group's next four platinum and gold albums, between 1979 and 1982. With the help of Deodato , the group's next album, Celebrate, became one of the biggest hits of their career.

Kool and The Gang separated amicably from their producer in 1983 and decided to create their own recordings in-house. The 1983 album In the Heart was produced by Khalis Bayyan (Ronald Bell), Kool & The Gang and engineer Jim Bonnefond , but in all following albums, Khalis Bayyan became the group's secret production weapon. From the mid-1980s until the early 1990s Khalis Bayyan kept the sound established, however; rock guitars began to replace horns, and their sound was transformed under the power of digital technology. Bayyan called his production set-up the IBMC or Itty Bitty MIDI Committee, using MIDI computer synthesizers and mixers. In the 1980s Bayyan produced the double-platinum Emergency and the gold Forever, on which he played almost all the instruments.

The biggest change of the 1980s, however, came with the departure of lead singer Taylor. The vocalist, who left in 1988, reportedly departed amicably with plans to make a solo album. Kool and The Gang replaced Taylor with singers/instrumentalists Sonnie "Skip" Martin, Odeen Mays Jnr . They released two studio albums, Sweat (1989) and Unite (1993). Taylor released three solo albums, produced by Khalis Bayyan and J. T. Taylor himself. There was a big news in the summer of 1995, Taylor returned the band and they released a new album, State of Affairs.
