I couldn't really think of a SRV/Jimi cover I liked more than the original (All along the watchtower aside - that's a definite upgrade by Jimi). The closest one was Jimi's Killing Floor (apparently Led Zep's The Lemon Song, though I don't really hear the resemblance).
So far, my favourite. I had hopes for the five finger death punch version of "House of the Rising Sun" but...ermm, no. Godsmack's Come Together was real good, but not quite beating the original for me. Guano Ape's Big in Japan, was a near hit, great energy in the track - though the vocal phrasing was a tad odd for me.
How I forgot this one is a mystery...were I not loving on Shirley Bassey atm, this would have been #3.
