In November 2015, Coldplay announced the Latin American and European legs of the "A Head Full of Dreams Tour" through their official website, with 28 stadium shows confirmed across 14 countries in Europe and Latin America the next year. A live album, Live in Buenos Aires, covering the tour, which was recorded during the last show in La Plata, as well as a concert film, Live in São Paulo, filmed around the world was released in November 2018. Grossing $523,033,675, the tour is currently the sixth highest-grossing concert tour in history. The first show of the tour was held at the Estadio Ciudad de La Plata in La Plata, Argentina, on 31 March 2016 and concluded at the same venue on 15 November 2017.
The tour consisted of eight legs, with a total of 122 shows across: Latin America, where they performed for the first time since the Viva la Vida Tour, Europe, North America, where they embarked on their very first stadium tour of the United States, Oceania, and Asia. The A Head Full of Dreams Tour boasted extensive laser light and pyrotechnic visuals similar to the Mylo Xyloto Tour, and also saw a reappearance of the Xylobands as a central part of the show's visual design. Marking the band's return to large-scale venues, after the brief and intimate Ghost Stories Tour, the tour visited stadiums and arenas across five continents. A Head Full of Dreams Tour was the seventh concert tour undertaken by British alternative rock band Coldplay, launched in support of their namesake seventh studio album A Head Full of Dreams.
