Michael Kamen wrote the orchestral arrangement for Metallica's studio version of “Nothing Else Matters.”
The song appears on Metallica's 1991 album and stands apart from much of the band's earlier material through its acoustic opening, restrained arrangement, and ballad structure. Kamen's orchestral work added a broader, cinematic dimension to the track while preserving its intimate core.
The studio credits list Kamen for orchestral arrangement and the London Symphony Orchestra among the additional performers. This is distinct from Metallica's later live collaborations with orchestras, particularly the S&M project, where Kamen arranged and conducted performances with the San Francisco Symphony.
Another possible source of confusion is the 2021 film Jungle Cruise. For that project, Metallica collaborated with composer James Newton Howard on a new orchestral arrangement. That later version does not change the credit for the original studio recording released on The Black Album.
