Hoppus had this to say about the band:
It's all very electronic right now. We have a girl singing part of the vocals. She and I are trading off vocals. Travis is going on the Warped Tour with the Transplants, and we'll record up until he leaves. And if the record's done at that point, we'll release the record later this year.
The female vocalist is Carol Heller, formerly of Get the Girl. In addition, Barker explained that the name of the band comes from the British dialing code since the band was originally discussed during a tour in the UK.
