On what date did recording sessions begin for Metallica, commonly called The Black Album?

Recording sessions for Metallica, commonly called The Black Album, began on October 6, 1990.

The sessions took place primarily at One on One Recording Studios in Los Angeles and continued until June 16, 1991. The long recording period reflected the band’s perfectionism and Bob Rock’s insistence on capturing stronger performances and a more cohesive sound.

Before the main sessions began, Metallica recorded demos on August 13, 1990, including early versions of “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters,” and “Wherever I May Roam.” Those demos are separate from the album’s formal recording period.

The October 6 start date is also distinct from the album’s release date. Metallica reached stores on August 12, 1991, after months of overdubbing, mixing, and preparation for the band’s most commercially successful release.
