I was reading the liner notes of a Jimi Hendrix cd I had bought years ago called First Rays Of The New Rising Sun. On a couple of the tracks Jimi is credited with playing both guitar and bass. The rest of the bass tracks are credited surprisingly to Billy Cox and not Noel Redding. This was the first Hendrix cd released after his death to contain never before heard tracks. A must have for all Jimi fans. Cheers.
