Dirty Rotten Imbeciles (also known as D.R.I.) are a crossover thrash band that formed in 1982.
The band never gained any mainstream audience, but were an influence on their contemporaries — most notably Suicidal Tendencies, Corrosion of Conformity, and S.O.D. — alongside whom they are considered the early pioneers of the sound that would later be called crossover thrash. This genre was also coined from their 1987 album Crossover.
