U2 have revealed that they are going to release songs that were recorded for an earlier album which they forgot all about.
The Irish rockers said they found several songs they recorded while making their 1984 album The Unforgettable Fire.
Frontman Bono and guitarist The Edge said they rediscovered the songs while they were remastering the record for its 25th anniversary reissue which is scheduled for release later this year.
Speaking to Radio 1, The Edge said: "I listened to some tracks that we're gonna release with the new Unforgettable Fire reissue, some new songs that we discovered that we'd recorded, back in that era - the '80s - that we're gonna put out. And they sound amazing."
Bono said that one track, entitled 'Disappearing Act', is "incredibly special".
The Edge added that the band have just completed putting the finishing touches to it in the studio.
He said: "Well, it was originally called 'White City', and it was a track we started with Brian Eno and Daniel Lanois back in 1983 when we were recording The Unforgettable Fire.
"And we discovered it about six months ago, and we dug it out and did some work on it in France a few weeks ago, and it's now finished."
Bono added: "It's 25 years ago, the drums, the bass and the guitar. And now, the voices. It is a strange, weird thing. And it's going out with The Unforgettable Fire reissue, but no-one's heard it."
