Over what dates were Metallica's main Black Album recording sessions held?
Answer
October 6, 1990–June 16, 1991
Metallica's main Black Album recording sessions ran from October 6, 1990, to June 16, 1991.
The sessions lasted roughly eight months at One on One Recording Studios in Los Angeles. That period included writing, tracking, retakes, editing, and the detailed production process led by Bob Rock.
The dates are earlier than the album's August 12, 1991, US release date. This distinction matters because recording, mixing, mastering, manufacturing, and promotion all occurred at different points in the album's release cycle.
The length of the sessions also reflects the band's change in working method. Rock encouraged more precise performances and more direct arrangements, contributing to the polished sound that distinguished Metallica from the band's earlier thrash-oriented records.
