After announcing they’re finishing up work on a new album, U2 have premiered a brand-new song in the trailer for the Nelson Mandela biopic ‘Mandela: Long Walk to Freedom.’ This is their first new song in three years, the NME reports. 

The song, which you can hear approximately halfway through the trailer below, was written for the movie, which is based on the former South African President’s 1994 autobiography, ‘Long Walk to Freedom.’ The film stars 'Wire' actor Idris Elba and lands in theaters Nov. 29.

That's just about the same time U2 hopes to finish up work on their new album, the 13th in their catalog and first since 2009's ‘No Line on the Horizon.’

In an interview with Irish radio station 98FM, bassist Adam Clayton revealed that the Irish rockers hope to complete the forthcoming album before the holidays. He added that he believes the new material will blend U2’s past and present.

“I think it’s a bit of a return to U2 of old, but with the maturity, if you like, of the U2 of the last 10 years,” he said. “It’s a combination of those two things and it’s a really interesting hybrid.”
