The trio embarked on a European tour the following fall, during which DeLonge felt increasingly conflicted both about his creative freedom within the group and the toll touring was taking on his family life. He eventually expressed his desire to take a half-year respite from touring, in order to spend more time with his family. Hoppus and Barker were dismayed by his decision, which they felt was an overly long break. DeLonge did not blame his band-mates for being disappointed with his requests, but was himself dismayed that they could not seemingly understand. In addition, DeLonge protested the idea of Barker's reality television series "Meet the Barkers", which was being produced for a 2005 premiere. He disliked television cameras everywhere, feeling his personal privacy invaded. Following the 2004 Indian Ocean earthquake, DeLonge agreed to perform at Music for Relief's Concert for South Asia, a benefit show to aid victims. Further arguments ensued during rehearsals, rooted in the band member's increasing paranoia and bitterness toward one another. He considered his band-mates priorities very different, coming to the conclusion that the trio had simply grew apart as they aged, had families, and reached fame. The breakdown in communication led to heated exchanges, resulting in his exit from the group. It was announced on February 22, 2005 that Blink-182 would be going on an "indefinite hiatus". DeLonge would not speak to Barker or Hoppus—whom he once considered his greatest friends—for several years. Despite this, Geffen Records president Jordan Schur reportedly told Barker that "any press you do, make sure you say everything is cool". Hoppus and Barker began laying down new ideas. Recording in Barker's basement and Hoppus' dining room, by necessity everything was electronic, with the two musicians experimenting with electronic drums, samples, keyboards and direct computer recordings. While away on a trip in April 2005, Hoppus participated in an interview with MTV News in which he revealed the band's existence. When the two regrouped, they decided to stop giving interviews about the new project. The band's name is a reference to the country code needed when placing a phone call to the United Kingdom, where Hoppus and Barker first discussed making music alone. The basement recordings were ambient and quiet by necessity. The addition of other members to +44 came gradually. In April 2005, Barker invited his friend Carol Heller to provide vocals on a track. Formerly of the all-girl punk quartet Get the Girl, Heller traded and shared vocals with Hoppus on most of the band's early demos.
