Musically, older rhythms from the late 1960s were recycled, with Sugar Minott credited as the originator of this trend when he voiced new lyrics over old Studio One rhythms between sessions at the studio, where he was working as a session musician. In the 1970s, Big Youth, U Roy, and I Roy were famous DJs. Around the same time, producer Don Mais reworked old rhythms at Channel One Studios, using the Roots Radics band. The Roots Radics would go on to work with Henry "Junjo" Lawes on some of the key early dancehall recordings, including those that established Barrington Levy, Frankie Paul, and Junior Reid as major reggae stars. Other singers to emerge in the early dancehall era as major stars included Don Carlos, Al Campbell, and Triston Palma, while more established names such as Gregory Isaacs and Bunny Wailer successfully adapted.
