Sound systems such as Killimanjaro, Black Scorpio, Silver Hawk, Gemini Disco, Virgo Hi-Fi, Volcano Hi-Power and Aces International soon capitalized on the new sound and introduced a new wave of deejays. The older toasters were overtaken by new stars such as Captain Sinbad, Ranking Joe, Clint Eastwood, Lone Ranger, Josey Wales, Charlie Chaplin, General Echo and Yellowman — a change reflected by the 1981 Junjo Lawes-produced album "A Whole New Generation of DJs", although many went back to U-Roy for inspiration. Deejay records became, for the first time, more important than records featuring singers. Another trend was "sound clash" albums, featuring rival deejays /or sound systems competing head-to-head for the appreciation of a live audience, with underground sound clash cassettes often documenting the violence that came with such rivalries.
