Fall Out Boy's Patrick Stump recently discussed the band's next full length with Billboard. The band already has a full album's worth of material,

Stump also notes:

[We are going in] some very different directions. There's lots of really bizarre ideas on there, everything from folk to … actually, I was experimenting with piano phases, like Steve Reich, the composer. There'll be some weird stuff, but at the end of the day, it's probably just gonna be a pop record."

The band is currently on tour supporting Infinity on High.
