What do you think of Lindsey Buckingham?
I think I do not have enough experience of him to make a valued judgement about his skills at this point in time.
Pink Floyd's "The Wall" album came out on a two-CD set some time ago, and I can play all of the first CD pretty much note-for-note, entirely by ear, with certain exceptions so that I hope will serve as proof of My abilities as far as guitar-playing is concerned. The exception is that the lead guitarist uses an axe that has a longer neck than the guitar I normally play on and so I do not have the range needed to play exactly one or two numbers on the album -but I can fake it quite well.
I would need some more time to listen to the object of your question before I could give an honest opinion as to his capabilities.
Cheers.
One of the most underrated conceptual artists of his time.
