What was the name of Metallica's 14-month tour supporting the 1991 album, commonly called The Black Album?

Metallica's 14-month tour supporting the 1991 album, commonly called The Black Album, was the Wherever We May Roam Tour.

The tour supported the band's self-titled fifth studio album and followed its rapid rise from influential metal group to global arena headliner. It lasted 14 months and included performances in the United States, Japan, and the United Kingdom.

The tour name came from the album track “Wherever I May Roam,” one of the record's five commercial singles. That song's travel-centered title suited a worldwide campaign that carried Metallica to major venues and new audiences.

The Black Album era also included major festival and stadium appearances beyond the core tour schedule. In September 1991, Metallica performed at the Monsters of Rock concert in Moscow, where about 1.6 million fans gathered for one of the first major open-air rock concerts held in the Soviet Union.

The tour's success reflected the album's unusually broad reach. Metallica could now headline on a scale that matched the record's international chart performance and massive sales.
