Guitar players are usually not remembered by the general public unless they have something else (like being cute). Worse for bass players and drummers, but the frontman/singer gets remembered. It was always a fight. Singer/guitarists is always easier but, like you said, usually considered non guitarist. I listened to the youtube you included and disclaimer taste/I am old, but then I listened to a lot of what he did: it is not very impressive. Sure, if you can do that live and long stretches that is talent but a good guitarist (what is the definition outside taste? that is a question, taste should not have anything to do with that)? Do you have something that shows he can do something? And the singing is just taste but without it would be better if you have.
