Rock n' roll has always needed an edge of danger. It needs a certain bite to elevate it above constant stream of disposable pop; & no where has this been more keenly observed than with arguably the greatest song writing team in the history of rock n' roll. It was the friction & between Mick Jagger & Keith Richards that enabled those great Rolling Stones songs to flow. Mick the ultimate showman vs Keith the ultimate rock star in this battle of the Glimmer Twins T-shirt.
