Overseen by producer T Bone Burnett, Lost on the River features a recently discovered stash of unfinished Bob Dylan lyrics from the 1967 Basement Tapes era at Big Pink in upstate New York. Dylan’s publisher offered them to Burnett, who assembled Elvis Costello, The Carolina Chocolate Drops’ Rhiannon Giddens, My Morning Jacket’s Jim James, Dawes’ Taylor Goldsmith, and Mumford & Sons’ Marcus Mumford to compose and play music to Dylan’s words. Sessions were held in a professional recording studio, and the roots-based songs vary, depending on where the lead vocalist takes the material.
