On what date was the 30th-anniversary remaster of Metallica's The Black Album released?

The 30th-anniversary remaster of Metallica's The Black Album was released on September 10, 2021. The anniversary edition revisited the landmark album three decades after its original 1991 release.

The project was issued as an expanded box set as well as in other formats. It included a remastered version of the album and a large collection of additional material, including live recordings, demos, and previously unreleased content.

Bob Ludwig handled the remastering at Gateway Mastering, while Greg Fidelman oversaw the content as executive producer. The package was designed to document both the finished album and parts of the long recording and touring story surrounding it.

The same date also marked the release of The Metallica Blacklist, a 53-track covers album featuring artists from many different musical backgrounds. That companion project connected the anniversary celebration to the album's continuing influence rather than simply reproducing the original record.
