Metallica on Monday announced "M72," a massive two-year world tour.

The announcement of the tour also came along with the release of a new song called "Lux Aeterna" and an album called "72 seasons Metallica." The tour will begin on April 27, 2023, and will last into 2024.

Tickets to the tour can be purchased starting on Dec. 2 for two-day tickets on the Metallica website or Ticketmaster and single tickets go on sale starting Jan. 20.

The band's first trip to the U.S. will be on Aug. 4 and Aug. 6 at MetLife Stadium in East Rutherford, New Jersey.

European tour dates include Amsterdam, Copenhagen, Helsinki, Madrid, Paris, and Warsaw, as well as Gothenburg, Sweden, and the German cities of Munich and Hamburg.

In North America, Metallica will tour in Canadian cities of Montreal and Edmonton, as well as Mexico City, Mexico.

U.S. cities include Chicago, Detroit, Los Angeles, Minneapolis, Seattle and St. Louis, as well as Arlington, Texas; Foxborough, Massachusetts; and East Rutherford, New Jersey.

The Los Angeles-based rock band claims there will be "No repeats," when they perform back-to-back concerts, so the shows will have different experiences.

Metallica has released 10 studio albums and has sold more than 125 million albums worldwide, with over 65 million records in the U.S.
