This track is from Hendrix’ second album “Electric Ladyland”. The song was originally written by Bob Dylan but it was Hendrix’ version that made it famous. Dylan himself says he prefers Hendrix’ version and feels like he is doing a Jimi Hendrix cover every time he performs the song – even though it’s his own song!
This is the initial solo over the into of the song right before the vocal enters with the first verse (0:09 – 0:18). All of the solos in this song taken together provide literally an encyclopedia of blues/rock lead guitar techniques.
