ICONIC Irish rock band U2 have unveiled their first new song since 2009.
The track appears in the trailer for the upcoming biopic movie on the life of Nelson Madela called ‘Mandela: Long walk to freedom’.
However the track may not appear on the band’s new album, as it was specifically written for the Mandela movie.
The movie stars Luther and The Wire actor Idris Elba in the title role and is based on Mandela's 1994 autobiography 'Long Walk To Freedom'.
The band’s last album was 2009’s 'No Line On The Horizon', however they are expected to release a new record next year.
It is reported the band are hoping to have the new collection finished by the end of next month, before deciding on a final track listing.
Rumoured collaborations on the new album include Coldplay’s Chris Martin and Danger Mouse.
