Although the music snobs just have to slate it though, it's the law apparently.
I think there's a little more to it than that; not my opinion, just the feeling I've got. Frinstance: Bari Watts (of Outskirts of Infinity and a very good Hendrix-style guitar player as well as a major fasn of Hendrix) was of the opinion that there are better mastered versions amongst the bootlegs and that it's the Hendrix family milking the memory for every last cent they can (I think his gripe is that it's not even 'proper' family).
Still, it's Jimi and it's awesome. It make sme wish for an afterlife in which he and Brian Jones jam to their heart's content.
