Who hasn't heard of Bob Dylan? Ever wondered about the behind-the-scenes solo acoustics and the umpteen number of retakes he did before the songs were actually recorded?

Sometimes a song becomes a chartbuster hit, and sometimes the song becomes a wreckage at the editing room studio.

The entire album called The Cutting Edge 1965-1966: Bootleg Series Vol.12 is now streaming on NPR Music The edition, which was not available for streaming earlier. is believed to include 'every note recorded' during Bob Dylan's sessions of 1965-66.

A disc featuring 20 different versions of 'Like a rolling stone' is also available.

The Cutting Edge 1965-66: The Bootleg Series Vol.12 will be accompanied with a book which includes some essays, rare photographs and memorabilia of the project by historian Sean Wilentz and author Bill Flanagan, RTT news reported.

The Cutting Edge documents an era when musicians huddled in small rooms and hammered stuff out.  During the 14-month-period in which Dylan recorded Highway 61 Revisited, Blonde on Blonde and Bringing It All Back Home, the making of the records were perceived as a divine process and managed impeccably with Dylan heard in the studio doing the off-camera work. The sessions take the listener back into the pre-digitization era.

Providing you with the entire background story, the end result of the recording seems like a saturation of inspiration, during the time when Dylan was an improviser, NPR reports.

In one of the audio takes, Dylan first attempts "Like a rolling stone" recorded in June 1965, one can hear Dylan playing the harmonica. He feels it is a bit rushed. Take 2 proceeds slowly. The performance begins to clear the next day. In each of the different takes, the band can be heard testing different tempos—then the master rendition hits bulls-eye, NPR said.
