DJ Grandmixer DXT (formerly Grandmixer D.ST as in Manhattan, New York City's Delancey Street on the Lower East Side, born Derek Howells) is credited with inventing turntablism, the rhythmic scratching of a record on a turntable, then using different velocities to alter the pitch of the note or sound on the recording, making the turntable a fully performable and improvisational instrument (Alberts 2002). He is also credited with greatly helping to popularize DJing through his scratching on Herbie Hancock's single "Rockit" from the Bill Laswell produced album Future Shock. The music video for "Rockit" was extremely popular on MTV.
