On July 4th, 1970, Jimi Hendrix performed at the Atlanta Pop Festival – just two months before the guitarist’s death.
By this point, Hendrix had assembled his Band of Gypsys, recruiting his Army buddy, bassist Billy Cox.
For a long time, fans traded this concert recording as a bootleg. In 1991, Warner Bros. released a four disc set which included the Atlanta concert and three others. The album, Stages is out of print.
Here is Cox’s isolated bass line for “All Along the Watchtower” from that performance. You can hear the vocals and the other instruments leak through in the background.
