+44

+44 was an American rock supergroup formed in Los Angeles, California, in 2005. The group consisted of vocalist and bassist Mark Hoppus and drummer Travis Barker of Blink-182, lead guitarist Shane Gallagher of the Nervous Return, and rhythm guitarist Craig Fairbaugh of Mercy Killers. 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.
