I should kick myself for even weighing in on these never to be resolved contests over who's good/who's bad. That said, to say that Keith Richards, Ron Woods, and Mick Taylor are "bad musicians" makes me wonder what standards are being applied here. These guys show up on pretty much everyone's "greatest ever" lists, Keith in particular. The thing I respect about the Stone's guitar work is that they eschew flashy "guitar god" pyrotechnics. Instead, they use two guitars to weave a bobbing and weaving rhythmic background that is musically greater than the single elements. If you can read music, check out the way their songs are put together and you'll see what I mean. You had groups like Clapton, Baker, and Bruce who were towering individual greats engaged in alpha male musical battles for dominance and many people respect that kind of group as an example of greatness. The Stones are the antithesis of that kind of musicianship imo. For them, it's a tribal musical thing, a sum greater than the parts.
