U.D.I. (which stood for Under Da Influence) was a hip hop duo from San Francisco, California. First formed in 1993, the duo consisted of emcees Big Quint and Dig. U.D.I. went on to release a few singles, one mixtape and three full length albums before disappearing by 2009. In 2015, Dig ended up dying from a shootout at the age of 42, thus putting an official end to U.D.I.
