Dirty Rotten LP is the 1983 debut release by the crossover thrash band Dirty Rotten Imbeciles. The album has a very gritty sound, and is considered one of the first thrashcore albums. D.R.I. had only existed for about four months, in which time they practiced every night and played a few shows in the Houston area. Dirty Rotten was recorded and produced by the band in the Brecht's parents' home which had a room walled with egg cartons as soundproofing where the band practiced. This is the long out-of-print (on vinyl) LP that was made from the "Dirty Rotten EP." The band realized, once they saw the prices on things, that to do their 22-song 7" as a 12" would only cost a little more. So, with that, D.R.I. did it and the "Dirty Rotten EP" became the "Dirty Rotten LP."
