The 2018 Polar Music Prize is awarded to the American band Metallica. Not since Wagner's emotional turmoil and Tchaikovsky's cannons has anyone created music that is so physical and furious, and yet still so accessible. Through virtuoso ensemble playing and its use of extremely accelerated tempos, Metallica has taken rock music to places it had never been before. In Metallica's world, both a teenage bedroom and a concert hall can be transformed into a Valhalla. The strength of the band’s uncompromising albums has helped millions of listeners to transform their sense of alienation into a superpower.
