The Rolling Stones may age, but their charisma doesn’t. Compare their early concert videos to 21st-century footage of their sold-out arena shows, and you’ll spot the same endearing qualities: Mick Jagger’s slinky moves and endless mugging for the camera, Keith Richards’ ragged toughness and Charlie Watts’ drowsy eyes as he sleepily lays down the loosest grooves in rock history. Yes, the Stones are cool, and they know it.
