A lot of folks confuse speed with skill. This is true in many realms of human endeavor, but quite frequently in the evaluation of guitarists. In my view, no performance so elegantly reveals the failing of such an evaluation as the White Album's version of George Harrison's While My Guitar Gently Weeps. Clapton's uncredited performance on this song is about as heart-rending a performance as I've heard on any instrument. He plays to the depths of human suffering, with only 23 years of life behind him at this point in his life.
