1984: Grandmixer D.ST Scratches at the Grammys
This was the scratch heard around the world. Although GrandWizzard Theodore and others had been scratching for the past several years, that distinctive sound had not yet become a familiar part of the musical soundscape. That changed in 1983 with the recording of “Rockit,” a track that paired jazz great Herbie Hancock with, among others, a young DJ known as GrandMixer D.ST. The sound of D.ST’s scratching — and especially the sight of him scratching on the telecast of the Grammy Awards ceremony in 1984 — inspired many to become DJs, including Mix Master Mike, Qbert, and Rob Swift.
