(FILES) In this April 25, 2011 file photo legendary American singer, songwriter, poet, artist and actor, Bob Dylan performs at the 22nd annual Bluesfest music festival near Byron Bay, Australia. Two years after his history-making electric performance, Bob Dylan holed himself up in a basement in upstate New York and played what became some of the most famous recordings never released. The prolific singer and songwriter, who had emerged as a defining voice of the 1960s, had suffered a motorcycle accident that forced him to take a break from the road. The involuntary convalescence ended up producing some of the most critically acclaimed work of his career. The 1967 recordings became what is considered rock history's first bootleg record: "Great White Wonder," a title that was simply a name for the vinyl's plain white packaging but occasionally became a moniker for Dylan himself. Nearly a half-century later, Dylan is releasing the entirety of the collection. The six-CD boxed-set, "The Basement Tapes Complete: The Bootleg Series, Volume 11," goes on sale on November 3, 2014 in Europe and November 4 in North America. AFP PHOTO / Torsten BLACKWOOD / FILES
