Steven Stein (19 August 1951) - better known as Steinski - is an American music and advertising producer.
Godfather of some of the zanier aspects of turntablism, Steinski created a succession of extra-legal works of studio art (the infamous "Lessons") that quickly became DJ landmarks and some of the most valued bootlegs in rap history.
Stein is still active as a radio DJ and compilation curator for innovative music from the past...
