U.D.I. (Under Da Influence) is a hip hop duo from San Francisco, California, primarily known for their influence in the Bay Area rap scene during the 1990s. Consisting of members Dig and Big Drawz, U.D.I. has made a significant mark with their laid-back, West Coast style, and street-centric lyricism.
