Coming out of the streets of Fullerton California, D.I. was formed in 1983 in a studio behind a pawn shop. D.I. was thrown to the forefront after the band performed "Richard Hung Himself" in the 1984 movie, "Suburbia". D.I. has toured extensively throughout North America and Europe, and everywhere they performed, left the audience not wanting the show to be over. The current members, which many have stated is the hardest hitting and most cohesive line up ever, is made up of Casey Royer on vocals, brothers Eddie and Joey Tatar as the rhythm unit of bass and drums, and lead guitarist Clinton Calton.
