Till,Agree with you on the quality, but I get no satisfaction from the re-mastered Stones discs- to me, the medium was the message, and their music, like Chuck Berry's, was made to be played through an overdriven, clipping old tube AM radio, loud, preferably in the back seat of a car. In a lot of their songs, like Street Fighting Man, they recorded parts into portable cassette players and then miked those into the consoles to get that sound.
Have always been a big fan of Keith's, as most guitar players have been. Just about no better at making good solid music, without the flash (except when Jack Jumps). A lot of his riffs and songs sound very simple but they're actually very complicated and tough to get the right sound. Dude also deserves some kind of special award for staying alive!
