One of the definitive rocksteady vocal groups, the Heptones were also one of the few to successfully make the transition to the reggae era. The group was fronted by Leroy Sibbles, who was not only an exquisite singer but also a talented songwriter, arranger, and session bassist at the legendary Studio One. Penning much of its own material, the group boasted one of the deepest catalogs of its time, full of high-quality numbers that were widely imitated for their close-harmony vocals, and widely recycled for their loose, liquid, melodic instrumental grooves. The Heptones were formed in Kingston in 1965, with a lineup of Sibbles, Barry Llewellyn, and Earl Morgan. At first they called themselves the Hep Ones, but a one-word name seemed to make more sense to fans, and the change was made accordingly. They made their first recording for Ken Lack's Caltone label that year, a strange ska adaptation of "The William Tell Overture" titled "Gun Men Coming to Town."
