Basically the first two tracks are jams with jazz keyboard player Larry Young, they may be from the Record Plant 15 May 1969. The third track is from Electric Ladyland studios, 15 June 1970 and has Chris Wood on sax and Dave Palmer on drums. This is often bundled up with the so called traffic Jams. The final track is from the Hit Factory and probably dates from August/September 1969 when Jimi still had the Gypsy Sun and Rainbows lineup.
