After The Jimi Hendrix Experience broke up, Hendrix got together with Billy Cox and Buddy Miles to form Band of Gypsys.

Who Knows is the lead track off of their only album, and the final release from Jimi before his death, later that year. One of my favourite things about it, is that they have Jimi Hendrix playing guitar (one of the greatest soloists of all time), but still dedicate over a full minute to a scat solo.
