Mick might’ve recorded vocals for some of these previously unreleased tracks and outtakes, but the boon of this extra disc, which comes as part of the 40th anniversary edition of Exile on Main Street, is the booming kick drum and bustle of Charlie Watts. The drummer kicked ass from behind his kit. And Bill Wyman’s bass playing stayed with the drums, sparred with them. It’s a lean, muscular and graceful display. Sure, Jagger still sounds good and Keith Richards is a walking, talking riff (check out the last track, the rockabilly “Title 5”). But it ain’t all about the Glimmer Twins. Did Watts and Wyman have a handle? If not, it’s not too late.
