Those are just remixes of tracks from the Axis album on disc one, I've heard. Disc Two has some very interesting material not related to the original album.
I have over sixty Hendrix releases . . . mostly of course unofficial. I find that much of the unreleased material I like better than the released.
I feel about Hendrix's music the way that I feel about Monk's, Miles', Mingus', Ellington-Strayhorn's and some others: I find value in all that I have heard.
