The Offspring. at Hit Factory Criteria Studios with
Danja. He was known as
Timbaland's protégé and had worked with
Britney Spears; the band felt working with him was a change of pace due to his production background. Danja played the band some synthesizer-based and beat-focussed ideas that they would write over. The group subsequently wrote the remainder of what would feature on their album. Atlantic gave the band a list of producers and albums they worked on for them to listen to. They returning to their hometown of Montreal to continue recording at Studios Piccolo. Further recording was done at Conway Studios, also in Los Angeles, and at Maratone Studios in Stockholm, Sweden. Marcella Araica engineered the Hit Factory sessions; Fortman and Jeremy Parker (who was also in charge of Pro Tools) engineered the NRG and Piccolo sessions; and
Max Martin, Doug McKean and Seth Waldmann engineered the Conway and Maratone sessions. All of the final recordings were produced by Fortman; he co-produced "When I'm Gone" and "The End" with Danja, and "Generation" with Danja and Martin. In September, the album was mixed by
Chris Lord-Alge at Resonate in Los Angeles, before
Ted Jensen mastered it at Sterling Sound in New York City. Unlike the previous two studio albums,
