Big post, but here are a bunch of live Hendrix tracks for your listening pleasure. What he left on the world in a short 3-4 years with the Jimi Hendrix Experience is remarkable. Definitely my favorite musician of all time, and I don't think that'll ever change.
Very few are deserving of covering Neil Young..... The Sheepdogs are of the select few. If you haven't heard their music before, definitely check them out.
