D.I.

This article is about the band. For other uses, see DI. D.I. is a Southern California punk band featuring ex-Adolescents and Social Distortion drummer Casey Royer on vocals. Royer formed the group after he and former Social Distortion original member Rikk Agnew, left the original Mike Ness crew.Since forming in 1982, D.I. has had many line-up changes and Royer has been the only constant member of the band. They broke up and reformed twice, sometimes with former members of The Adolescents and Social Distortion (including the Angew brothers Rikk and Alfie). During their years of touring and making albums, the band has never achieved mainstream success, but they have been an influence on later punk bands, including The Offspring.
