On which song did Metallica add an orchestra for the 1991 album Metallica, known as The Black Album?

Metallica added an orchestra to “Nothing Else Matters” for the 1991 album Metallica, known as The Black Album.

The orchestral arrangement was one of the production choices encouraged by Bob Rock. The album also used cellos on “The Unforgiven,” giving both songs textures that were unusual for a heavy-metal record of the period.

“Nothing Else Matters” began as a personal song James Hetfield wrote while on tour. Although he initially regarded it as too personal for Metallica, the band developed it into one of the album’s defining tracks. Its clean guitar opening and orchestral coloring helped make it a crossover success.

The song was released as the album’s third commercial single on April 20, 1992. It reached number six in the United Kingdom and Ireland, and its reflective style broadened public ideas about what a Metallica ballad could sound like.
