Well his vocal form was great (although since I was in the 1st row for the whole gig I didn't have the best sound). The concert was shortened a bit because the place was too hot for him so I guess his health is not 100% and he needs to be careful about many things.
All in all he is as great as ever, considering his open heart surgery not so long ago.
Frusciante
Jimi Hendrix
RHCP
Radiohead
Manu Chao
Tracy Chapman
B.B.King, Muddy Waters, Lee Hooker, Miles Davis, etc...
Clapton, Susan Tedeschi, Rudy Rotta...
Don't know about the number or the order (frusciante is definitely the N°1 thou, and the blues kings should definitely not be in the bottom of the list!) but it's all about the the mood
Didn't spend too long thinking about this, because it would be impossible to choose. I'll go for something like this:
Kyuss
Queens of The Stone Age
Led Zeppelin
Red Hot Chili Peppers
Arctic Monkeys
Mark Lanegan
The Doors
Patsy Cline
Jimi Hendrix
