Heavy metal titans Metallica embarked upon their electrifying WorldWired Tour in 2016, coinciding with the release of their tenth studio album, Hardwired... to Self-Destruct.
Over a four-year period, Metallica played 143 shows spanning four continents. Over four million metalheads were treated to performances of songs from the band's latest album, as well as crowd-pleasing hits like Master of Puppets and For Whom the Bell Tolls.
However, the Australian leg was cancelled due to frontman James Hetfield's struggles with addiction, while the South American leg was postponed until 2022 due to the COVID-19 pandemic.
Despite these setbacks, the tour still grossed $433.8 million, the equivalent of $538 million (£426m) in 2024 money. This makes it the highest-grossing tour in the band's decade-spanning career.
