Massive Attack were in awe of Damon Albarn when they asked him to collaborate on their forthcoming new album.
Band member Grant 'Daddy G' Marshall told Gigwise: "How do you produce Damon? You kindly ask Damon. You say 'Damon, we've got a track that we want you to do and here are the lyrics, would you like to have a look at the lyrics?"
The album - the group's first since 2003's '100th Window' - is scheduled for release in February 2010.
