Though Kool & The Gang ruled the charts during their ‘70s and ‘80s disco heyday, they originally found their roots making soul jazz in the late ‘60s. Early tracks like “Breeze & Soul” and “Dujii” boast interweaving horn lines and tasty drum breaks, while the stomping “Jungle Jazz” recasts their early hit “Jungle Boogie” with a heavier beat and some fluttering jazz flute.
