Since the early 1980s, Fullerton, CA. has been the breeding ground for legendary Southern California hardcore punk bands such as The Adolescents, Agent Orange and Social Distortion. Among these punk pioneers is D.I., a band that has remained in the scene by staying true to the Orange County punk sound and attitude that inspired them and helped launch a punk rock movement. After forming in 1982, D.I. was first thrust into the limelight when they performed “Richard Hung Himself” in the 1984 film, “Suburbia,” directed by Penelope Spheeris. The song, off D.I.'s 1982 self-titled EP, produced another significant event in the history of D.I. when metal band, Slayer crossed musical boundaries and covered it in their 1996 album, “Undisputed Attitude.”

While the band has seen many lineup changes through the years, front man Casey Royer has remained the heart of the band as the only constant member. While participating in fellow reputable bands from Fullerton, the Adolescents and Social Distortion, Casey kept D.I. alive, many times with the help of his musically talented friends, as they'd cover for missing players. Casey's distinct vocals are enhanced with his witty social commentary in which he attacks California law's injustices. (Click Here to Read the Entire Bio)
