"When it comes to Cliff Burton, it's a tale of what could have been. A legend in the making with Metallica, Burton was only 24 when he was killed after the band's tour bus crashed on an icy road in rural Sweden in 1986. In the wake of that tragedy, Burton's legacy continued to live on even as Metallica became one of the biggest bands in the world. The hair-swinging, spaceship-sounding, bass-playing Burton was a major presence on the band's first three albums that remain metal masterpieces. For a true taste of Burton's greatness, listen to his work "(Anesthesia) – Pulling Teeth," "The Call of Ktulu," "For Whom the Bell Tolls," and "Orion.""
