D.I. is the eponymously titled debut EP by the American hardcore punk band D.I., released in 1983 through Revenge Records. It was recorded by the band's early lineup of Casey Royer, Rikk Agnew, Tim Maag, Derek O'Brien, Steve Roberts, and Frederic Taccone. The EP was re-released in 1987 by Triple X Records as Team Goon with four additional tracks: The first three—"Nuclear Funeral", "The Saint", and a cover version of Gary Glitter's "Rock and Roll Part II"—were recorded by the band's mid-1980s lineup of Royer, John Bosco, Steve Garcia, and brothers Rikk and Alfie Agnew, while the fourth—a cover version of Devo's "Uncontrollable Urge"—was recorded by the late-1980s lineup of Royer, Bosco, Steve Drt, Sean Elliott, and Hedge.
D.I. received a positive review from Ruth Schwartz of Maximumrocknroll, who said "D.I. have well-executed, concise songs with interesting but not necessarily innovative arrangements. There are a lot of obvious influences here—Flipper, Adolescents, Circle Jerks, Misfits—but the witty lyrics and good production make it plenty entertaining."
