Well, um, yes it is! Unexpectedly and released free on itunes on 9th September and available until 13th October. Called Songs of Innocence, and possibly part of a trilogy with the next album to come later this year (maybe, we know what U2 are like!)
It is a look back at the genesis of the band and the relationships,events and experiences that formed them - especially Bono, whose lyrics are achingly honest.
I'm still letting the music sink in and settle, but I can say, though it is not a classic, I do like what I've heard. A full review will follow in time.
