Four songs from Metallica's The Black Album were demoed on August 13, 1990.
The session produced early versions of “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters,” and “Wherever I May Roam.” These recordings captured key ideas before the band began the main album sessions at One on One Recording Studios in Los Angeles.
The date is notable because it shows how quickly the album's central musical identity was taking shape. “Enter Sandman” would become the lead single, while “Nothing Else Matters” developed into a major power ballad despite initially being a private piece James Hetfield had written while away from home.
The four demos were recorded in Lars Ulrich's home studio, often referred to as The Dungeon. They should not be confused with the separate demo of “Sad but True,” which was recorded on October 4, 1990. Anniversary editions later made many such archival recordings more widely available.
