Dirty Rotten Imbeciles (often abbreviated, and referred to, as D.R.I.) are an American crossover thrash band that formed in Houston, Texas in 1982. The band is currently composed of two of its founding members, vocalist Kurt Brecht and guitarist Spike Cassidy, as well as drummer Rob Rampy and bass player Greg Orr.
D.R.I. never gained a mainstream audience, but the integration of their hardcore punk roots with thrash metal influences was a stylistic catalyst for their contemporaries — most notably Suicidal Tendencies, Corrosion of Conformity, Stormtroopers of Death, the Cro-Mags, Nuclear Assault and Cryptic Slaughter — alongside whom they are considered to be one of the major pioneers of what would later be called "crossover thrash", along with Adrenalin O.D., with both bands having a heavy influence on modern thrash metal.
To date, D.R.I. has released seven full-length studio albums. Other than three new songs on the 2016 EP But Wait...There's More!, they have not released a full-length studio album since Full Speed Ahead in 1995. Despite this, the band has continued to tour almost every year, and gone on hiatus intermittently, notably between 2004 and 2009, when Cassidy was diagnosed with colon cancer. In 2013 Ed loco of Houston based UYUS, Humungus, and Verbal Abuse graciously filled in for Spike on the South American leg of their tour. Since at least 1998, D.R.I. has been working on their eighth full-length studio album, which remains unreleased.
