Speaking to Rolling Stone, the U2 guitarist said, "There's a bunch of amazing pieces that we didn't finish from the work we did in Fez [for No Line On The Horizon], and there's the songs we started with Rick Rubin, some of which are amazing songs that I'd love to get back to at some point.

"The one thing is we'd love to follow this album up sooner rather than later," Edge added. "I don't think we'll have over three years or whatever it was between the last two records." - more on this story
