Grove music online WWW site, March 26, 2004 (DJ (Disc jockey): i. A term first used in the early 1950s to describe those presenters who played and helped select the popular hits of the day for broadcast. ii. A performer in dance clubs who creates continuous music for dancing through the manipulation by mixing and joining of pre-recorded tracks. The DJ came to the fore in the USA in the late 1970s and early 80s at block parties, where two turntables and a mixer were used to create a seamless blend of beats, riffs and hooks as a backdrop for early rappers. With house music, DJ performance developed further with beat-mixing, which created a lengthy and seamless mix between records. By the mid-1990s, leading DJs performing at clubs drew comparable audiences to those of traditional concerts, often commanding higher fees and dominating the album charts with DJ-mixed compilations)
