MUMBAI: On Thursday, 13 November at the Montalban Theatre in Hollywood, a private concert featuring artistes Marcus Mumford, Elvis Costello and HAIM took place after a screening of the new Bob Dylan documentary 'Lost on the River: The Basement Tapes Continued'. Music producer T Bone Burnett spent two weeks secluding himself with prominent musicians of different ages and genres to record 43 adaptations of lyrics and drawings rediscovered years later by Dylan himself from his 1967 recordings at Woodstock.

The ensemble assembled by producer T Bone Burnett just released 'Lost on the River: The New Basement Tapes,' an album consisting of newly completed songs set to lyrics Dylan wrote circa 1967 and stashed away until recently. The New Basement Tapes band, which includes Elvis Costello, Mumford & Sons' Marcus Mumford, My Morning Jacket's Jim James, Carolina Chocolate Drops' Rhiannon Giddens and Dawes' Taylor Goldsmith performed the hit Dylan songs to a filled audience. The upcoming sibling trio HAIM also made an appearance to add background vocals to a couple of numbers along with actor Johnny Depp, who slinked onstage to strum a low-slung electric guitar on a few more tracks.

"We did not know we were doing this until yesterday," Burnett told a crowd that included Capitol Music Group chairman Steve Barnett, Jakob Dylan, comedienne Sarah Silverman and actor Michael Sheehan. Mumford said they spent a single day learning the songs for the concert.

The documentary's director Sam Jones told earlier, "I am a musician, and I spent many years trying to emulate the idea of friends getting together in a basement plying music. The basement tapes started that trend of we do not have to be in a recording studio. We can be in a house or we can be in a cabin in the woods, and we can record. I love that aesthetic and that idea, so I was in the minute they asked."

Internet sources claim that although it was their first time working together as a group, the musicians ditched the formal recording process to see what creative results could stem from simply making music without expectations.
