On what date did Metallica record four demos for The Black Album?

Metallica recorded four demos for The Black Album on August 13, 1990.

The demo session captured early versions of “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters,” and “Wherever I May Roam.” These recordings came before the main album sessions and documented the developing direction of the band’s next studio project.

The date is significant because the songs were written in a relatively concentrated period during mid-1990, before recording began in earnest at One on One Recording Studios in Los Angeles in October. “Enter Sandman” was the first of the album’s songs to be written, but its lyrics were completed later than the basic musical idea.

Several nearby dates can cause confusion. “Sad but True” received a demo on October 4, 1990, while the album’s lead single was released on July 29, 1991. The August 13 date refers specifically to the four-demo session, not to the album’s release or final recording.
