Bob started releasing his Bootleg Series in 1991 and he recently announced plans to release the the next edition, The Bootleg Series, Vol. 10 - Another Self Portrait (1969-1971), on August 27th. The four disc project will feature never-before-heard material from Dylan's original acoustic sessions and outtakes from Self Portrait along with select cuts from 1968's Nashville Skyline and 1970's New Morning.
Dylan originally began recording Self Portrait in New York City in April of 1969 but then stopped recording until March 1970. The break didn't make much sense since Dylan was actually recording a lot of covers.
Al Kooper, who played organ on the project, told Rolling Stone, "It was bizarre. He wasn't writing any of the songs, which is an important part of a Bob Dylan album. He had a pile of Sing Out! magazines and he was taking the songs, as in the chords and lyrics, straight out of them. They were his main feed, then they pulled other things like 'Mr. Bojanges' and 'The Boxer.' I was like, 'Yikes!' At one point we recorded 'Come a Little Bit Closer' by Jay and the Americans. Hopefully nobody ever hears that."
