Yeah, Brian Jones was responsible for a lot of that extra something on most early Stones song. He taught Keith a lot. Without him the group was a bit murkier and grungier and I don't think as distinctive. Not to say Keith is being a Jimmy Page and allowing himself to take credit for things he didn't do, he is a cool guy and knows we're all basically one race under the skin. His solo recording 'Take It So Hard' is an all time favorite.
Tallying up riffs is a bore (and there are riffs from other instruments reinvented for guitar, especially that came from saxophone players) but you'd think Hank Marvin of The Shadows might figure extremely prominently! Sheesh.
