As U2 resumed their world tour in Italy last week, Bono has reflected on the poor performance of their last album, the rather weak No Line On The Horizon, admitting to Rolling Stone that the album was ‘not very accessible, lyrically or musically.’

The band have also reworked their set to effectively drop most of the songs from the album. His Bononess has also revealed that the band are playing several new unreleased songs in the shows, and also have around three albums of material up their sleeve for possible future release. The songs include ‘Return of the Sting Ray Guitar’ and ‘Glastonbury,’ and ‘North Star.’ an unfinished acoustic ballad. As for the unreleased songs, Bono is musing on how to release them.

‘We have Songs of Ascent, which is the meditative work that was meant to complement No Line on the Horizon. We’ve got a rock album. We also have a club-sounding album. And then we have the Spider-Man [musical] stuff. Across those four, there are 25-30 songs. Now we have to decide how we go about releasing them?’
