Stewie...great post, man. I'm going to use it as reference.
It can be argued whether E.C. is a blues guitarist, but the liner notes to "From The Cradle" quote Clapton as saying that's how he essentially sees himself, pop ditties notwithstanding.
Personally, I think he's diluted his style too much over the years to be considered purely a "blues" guitarist. Thirty years ago, maybe.
But what do I know, I'm not God, EC is.
