D.R.I.

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 and would later relocate to San Francisco, California. The band is currently composed of two of its founding members, lead vocalist Kurt Brecht and guitarist Spike Cassidy, as well as bassist Greg Orr and drummer Danny Walker.

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, Adrenalin O.D., and Cryptic Slaughter – alongside whom they are considered to be one of the major pioneers of what would later be called "crossover thrash". These bands had a heavy influence on modern thrash metal.

As of 2026, D.R.I. has released seven full-length studio albums. Apart from 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 for almost every year, and gone on hiatus intermittently, notably between 2004 and 2009, when Cassidy was diagnosed with colon cancer. Since the late 1990s, D.R.I. has been working on their eighth full-length studio album, which remains unreleased.
