The genre "crossover" was coined from a 1987 release, which basically sums up the sound of the thrash metal/punk-hardcore hybird.
Evolving out of a defunct hardcore band called the Suburbanites. Singer Kurt Brecht, drummer Eric Brecht (his brother), and bassist Dennis Johnson had all played in that outfit, and with new guitarist Spike Cassidy in tow, they renamed themselves Dirty Rotten Imbeciles, after a frequent insult from the Brechts' father (who objected vehemently to their rehearsals). Started out as a punk band, then got thrashier and thrashier.
DRI is considered the first band that used the blast beat on their song "No Sense!".
Other than touring constantly, D.R.I. has released no new material since their last album, Full Speed Ahead, was released in 1995.
