Fall Out Boy have discussed the follow up to 2013 EP Pax AM, saying that they have a few pieces in the works and may turn their talents to rapping.

Speaking at this months gig at Wembley Arena, Pete Wentz and Patrick Stump stated that their collaboration with Ryan Adams was very much a spur of the moment thing and that the follow up may be along similar lines. However Wentz reiterated that it won't be coming when fans are ready for it, rather it will be a surprise. 

"I would say that we're not very far along but I would say that we're also not focused," said Pete. "We're the kind of band I think that with version 2.0 of what we're doing right now... Like Pax Am was very spur of the moment and I think we have other spur of the moment things that will and are happening, but we'll get sidetracked."

"I feel like we're definitely at the point where we're doing fall Out Boy the way we want to and using the methods we want to use. At the last time you expect it I would say expect it," he elaborated. 

Following on from the comments Wentz jokes that they may become rappers: "I'd like to say that we will be rappers from now on and all past material will not be performed anymore." To which Stump added: "sincerely, we're growing beards, wearing sunglasses and appearing on David Letterman."
