"Sister Morphine," the heart of guitarist Mick Taylor's first full studio album with the Stones, doesn't get the airplay of "Brown Sugar" or "Wild Horses." But it's one of the most vivid, horrifying songs about drug abuse ever recorded--as Mick Jagger sings "from my hospital bed," the ringing guitars of Taylor and Keith Richards build to full catharsis behind him. On that and lighter songs like the countryish "Dead Flowers" and the rocker "B**ch," Charlie Watts establishes himself as rock's prototypical drummer. He's creative and propulsive and knows how to swing, but he never overwhelms the song or the other Stones.
