Kool & the Gang is an American jazz, R&B, soul, funk, and disco group, originally formed in 1964 as the Jazziacs based in Jersey City, New Jersey. They went through several musical phases during their recording career, starting out with a purist jazz sound, then funk and R&B, progressing to a smooth pop-funk ensemble, and in the post-millennium creating music with a modern, electro-pop sound. They have sold over 70 million albums worldwide.
The group's main members over the years included brothers Robert "Kool" Bell (Muhammad Bayyan) on bass and Ronald Bell (Khalis Bayyan) on tenor saxophone, lead vocalist James "J.T." Taylor, George Brown on drums, Larry Gittens on trumpet, Dennis Thomas on alto saxophone, Claydes Charles Smith on guitar, and Rick West (Westfield) on keyboards.
