Metallica – For Whom The Bell Tolls [live, Donington, 17th August 1991]
During the Monsters of Rock Festival on 17th August 1991, Metallica was the 4th band to play, just before headliner AC/DC.
This was one of the songs they played, the third track from their second album Ride the Lightning (1984). The chromatic introduction, which is usually mistaken for an electric guitar, is in fact the bass guitar through distortion and wah-wah. The intro was written by the late Cliff Burton before joining Metallica.
