A couple of clips where Izzy performs with Guns'n'Roses years after his departure. When you look at the other guitarists in the first clip and then Izzy, it's rather obvious that he's not in the least interested in looking impressive and cool in front of big rock audiences.

(2012) Here Izzy looks like Russ Ballard. https://www.youtube.com/watch?v=JH6JoFJXQcA
This was also interesting. Slash, Duff (Velver Revolver) and Izzy performing a G'n'R track. It's weird how Izzy's guitar is louder than Slash's. His guitar is very prominent in the choruses. Or maybe the VR guy plays Izzy's part too and together they busy Slash here and there. https://www.youtube.com/watch?v=5xydtQEARP4
I've always felt that the second verse in Pretty tied Up describes how Izzy felt about the band at the time. What he felt they had become or were about to become.
