Kool & the Gang is an American group formed in 1964 in Jersey City, New Jersey, originally as the Jazziacs. The founding lineup included brothers Robert “Kool” Bell and Ronald Bell, along with Dennis “Dee Tee” Thomas, Robert “Spike” Mickens, Charles Smith, George Brown, and others. Over the decades the band evolved from jazz‑influenced instrumental work to a signature blend of soul, funk, disco, and pop, producing hits such as “Celebration,” “Jungle Boogie,” and “Ladies’ Night.” The group has sold more than 70 million albums worldwide and continues to tour with a lineup still led by founding members Robert “Kool” Bell and George “Funky” Brown.
