I'd go for Live at Winterland, although it isn't a recent release. Actually it was my first ever cd, somewhere in the 80's. Hell, I didn't even own a cd-player then! Anyway, last week I played it, and it sounded pretty good, and he was doing a good show.
Live Hendrix
Of the recently released Hendrix concerts...Isle of WIght,Rainbow shows, and Berkeley 2nd show...which one has the superior sound quality...
