+44

+44 was announced in April 2005, only three months after Blink-182 had announced their indefinite hiatus. The band originally consisted of elements not usually present in Blink-182's work, namely electronic drums, samples, keyboards and direct computer recordings.

As work continued on the demos, Get the Girl vocalist Carol Heller was invited by Hoppus and Barker to audition her vocals. Heller's performance was agreeable enough to the band and as a result the three kept working on more songs together. The band's lineup changed again early 2006, with the addition of guitarist Shane Gallagher.

In order to progress with their demos, Barker and Hoppus acquired a studio, a move which marked a "turning point for +44." The band began working solely in the studio they had purchased, playing live drums, guitars and vocals. The band's original electronic elements became less evident, but still remained a key feature. As a result, Heller found she wasn't compatible with the band's direction, and with the addition of her wish to start a family, she left the band. The vocal work that Heller contributed is still present in the song "Make You Smile". After this, Hoppus, Barker, and Gallagher were left to find a new backing vocalist. Guitarist Craig Fairbaugh of Mercy Killers then joined the band.
