This Altamont discussion has got me thinking about '69 Stones and '69 Dead. While '72 Stones and '72 Dead is quite often acknowledged as peak Stones and peak Dead, there is something about the heavy, muscular sound of both bands in '69 that just cannot be beaten or replicated. Both bands reflected the tenor of the times as a weighty, apocalyptic sound infused their music, especially live. Both were playing primal rock & roll at the top of their game. Marimbas were replaced by Keith's attacking guitar on "Under My Thumb," and despite Mick saying it was, it was not "all right."
