Dirty Rotten Imbeciles started out as a speedy hardcore band in Houston in the early '80s. The band was renowned for its short songs, its leftist politics and the frenzied passion of its playing. D.R.I.'s appropriately-titled, landmark 1987 album, Crossover, lived up to its name by introducing a sound that fully integrated breakneck hardcore rhythms with a thrashy guitar attack, which the group had been developing all along. Marketed in the late '80s to both metalheads and hardcore fans, D.R.I. seemed to find an easy audience in anyone who loved aggressive music with anti-authoritarian lyrics. During the course of four more albums, up to 1995's Full Speed Ahead, D.R.I. mastered a sound that can be heard in virtually all metal and punk hybrid groups today. The outfit, which still hasn't put out its rumored eighth album, remains a potent live act.
