Weinman started to program drums daily for two months out of desperation. On June 15, the band announced the title of the album as well as confirming the departure of Pennie. "Ire Works" was released on November 13, 2007, through Relapse. Despite the inner turmoil, when the record was finished the band was more satisfied with it than with any of the previous ones, calling it a "turning point". The album debuted on the Billboard 200 at number 142 with 7,000 copies scanned, but was later corrected when it was revealed that Relapse did not account for album pre-release sales, increasing the number of total copies sold to 11,000. "Ire Works" had been a critical and commercial success, with the album being on many critics' top ten lists, making it the band's most critically successful album. Jason Lymangrover of AllMusic stated that "[if DEP aren't careful and continue down this innovative path, they could easily be labeled the Radiohead of metalcore." On February 6, 2008, the band had two songs from "Ire Works" broadcast on two television programs in the United States. The song "Milk Lizard" was featured on the "" episode "Playing With Matches", and the band performed live the song "Black Bubblegum" on "Late Night with Conan O'Brien". Missing from the new line up was Benoit, who had left the band because of injury. Although assured his place in the band is secure should he ever be able to perform again, Jeff Tuttle formerly of Heads Will Roll and Capture the Flag took his place on stage. Tuttle, however, does not make an appearance on the record.
