I'd have to agree that the band as a unit is it's greatest asset. And their output between about 1965 and 1972 was pretty tight.

I'd say Keith if we're going individual players,but I agree with all the sentiments expressed that the band's main appeal is how tight and kinetic they were as players up till '73 or so(Especially on Let It Bleed and longer workouts like Can't You Hear Me Knocking which really showed how capable they were as musicians),when the drugs etc started to take their toll.
