"The Unforgiven" is a power ballad by American thrash metal band Metallica. It was released as the second single from their eponymous fifth album Metallica. Though one of the slower tracks on the album, its chord progression is distinctly one of the heavier. The song deals with the theme of the struggle of the individual against the efforts of those who would subjugate him.The song has since spawned two sequels (both in name proper as well as thematically, albeit not musically), in the form of "The Unforgiven II", from the album ReLoad, and "The Unforgiven III", from the album Death Magnetic.HistoryLars Ulrich explained that the band wanted to try something new with the idea of a ballad - instead of the standard melodic verse and heavy chorus (as evidenced on their previous ballads "Fade to Black", "Welcome Home (Sanitarium)" and "One"), the band opted to reverse the dynamic, with heavy, distorted verses and a softer, melodic chorus, played with classical guitars. The opening section contains percussive instruments performed by Ulrich, and also a small amount of keyboards.The horn intro was essentially taken from The Unforgiven (a Western movie) and then reversed so its source would be hidden, as Hetfield later explained on Classic Albums: Metallica - Metallica.
