U2 have been busy at Electric Lady Studios in New York this past week putting the finishing touches on a new album, the band's first since 2009's "No Line On The Horizon."

Rolling Stone reports the activity at the New York studio is where producer Danger Mouse was completing his mixing work on the new, untitled album, reportedly due in the fall.

U2 have been working steadily on this album since before wrapping their 2009-2011 world tour. They originally planned on releasing a second series of songs from the "No Line On The Horizon" sessions titled "Songs Of Ascent," but it appears they've scrapped that idea in favor of fresh material. They worked briefly with Lady Gaga producer RedOne, but soon settled on Danger Mouse.
