The Dillinger Escape Plan (sometimes abbreviated to DEP or TDEP) is an American metalcore band from Morris Plains, New Jersey. The band performs a fast-tempo, technically proficient style of metal popularly known as mathcore or technical metalcore. The band recorded their first EP with Relapse Records in 1997 entitled Under the Running Board. Two years later, their album Calculating Infinity was met with great acclaim from both underground and mainstream press. The band gained notoriety in the hardcore scene for the intensity of their performances, which have incorporated light shows, fireworks, fire breathing, and other special effects.
While the band's lineup has changed over the years, in part due to a variety of injuries, guitarist Ben Weinman and former drummer Chris Pennie have been present in many of the lineups. After the departure of vocalist Dimitri Minakakis in 2001, the band held a nationwide search and selected Greg Puciato as the new singer. The band has since released two full length albums with Puciato on vocals: 2004's Miss Machine and 2007's Ire Works.
