Elvis Costello and Marcus Mumford have signed up to help music producer T Bone Burnett turn lost Bob Dylan lyrics into songs for a new tribute album.

My Morning Jacket star Jim James and Rhiannon Giddens of Carolina Chocolate Drops have also joined the project.

Lost On The River: The New Basement Tapes is set for release this autumn (14) to coincide with a new documentary called Lost Songs: The Basement Tapes Continued, directed by Sam Jones.

The lyrics come from Dylan's 1967 Basement Tapes sessions.
