Metallica's 1991 album, The Black Album, was primarily recorded in Los Angeles.
The main sessions took place at One on One Recording Studios in Los Angeles, California. The band worked there with producer Bob Rock during an extended recording period that ran from October 1990 into June 1991.
The sessions were more collaborative than Metallica's earlier working methods. Rock wanted the musicians to perform together in the same room, which helped create the album's tight, forceful ensemble sound but also led to frequent creative tension.
The location can be confused with Vancouver, where the band spent about a week working at Little Mountain Sound Studios. That short visit was part of the broader production process, but Los Angeles was the principal recording base.
