Malcolm Greenridge (born 7 July 1974), better known by his stage names E.D.I. and EDIDON (formerly E.D.I. Mean), is an American rapper, record producer and member of the Outlawz. In the third grade, Greenridge became friends with Katari Cox, who would later introduce him to his cousin Tupac Shakur. In 1994, Greenridge, Cox, Yafeu Fula and Mutah Beale formed the group Dramacydal, and featured on Shakur's 1995 album Me Against the World. The following year, Dramacydal was merged into the Outlawz, with Shakur giving each member of the group an alias from an enemy of the United States. Greenridge was given the name E.D.I. Mean after former Ugandan president Idi Amin.
In 1996, E.D.I. Mean made several appearances on Shakur's album All Eyez on Me, featuring on the songs "Tradin' War Stories", "When We Ride" and "Thug Passion". Shakur's posthumous album The Don Killuminati: The 7 Day Theory was released the same year, and featured E.D.I. on the songs "Bomb First (My Second Reply)", "Life of an Outlaw" and "Just Like Daddy". In 1997, the Outlawz signed to Death Row Records and appeared several times on Shakur's 1997 album R U Still Down? (Remember Me), with E.D.I. both rapping and producing. Two years later, Outlawz released their debut album, Still I Rise.
