Yes, his playing was a bit sloppy as I noted above, but ahhh... what playing it was! It's my understanding that the first guitar player to use feedback in his leads was Jeff Beck, but Hendrix was close on his heels and he took it 5 leaps beyond Beck. I suspect that if Jimi lived, he would have cleaned up his style a bit, and would not be as dependent on high volume and feedback. He was a genius and would have evolved. Show off? Of course he was! He played behind his head, with his teeth, and used obviously sexual poses and moves. But, he borrowed this from guys before him like Chuck Berry and Buddy Guy. But, then he dropped a bit of acid and Voila! You have the first and best psychedelic/blues/power trio of all time. I don't know if any performer in history looked so different from the previous performers in rock and roll. Maybe Devo? Some early punk? The look was part of the uniqueness and today's rock and rollers should understand. It's the context, baby.
