[1][2] After months of speculation, the tour was teased by Axwell Λ Ingrosso during a show in New York on May 27, 2018,[3][4] and was confirmed by Steve Angello later in June in an interview with Sydsvenskan.

[12][13] That day the group held a press conference which they revealed that a worldwide tour would occur the following year and their first stop would be Stockholm's Tele2 Arena.

[15] At the end of the month, following another successive timer and billboards appearing in respective cities, Swedish House Mafia announced they would play Tinderbox, Stavernfestivalen, Frequency Festival, and Creamfields as part of their tour,[16] whilst February 2019 saw Ultra Europe, Ultra Korea, and Lollapalooza added to the list.

[31][32][33] Until the group members Axwell released 2 songs "It Gets Better (2019 Version)" in November 2021 and "Underneath it All" in July 2022 via Dropbox[34][35] Swedish House Mafia's set as of their first show, at Stockholm's Tele2 Arena on May 2, 2019.

[51][52][53] However the date turned out to be a give away for 33 life time passes to all future Swedish House Mafia shows.

[54] The tour ended with Swedish House Mafia opening the 2019 Singapore Grand Prix to a crowd of 45,000 people.

However the new deal would supposedly enable Swedish House Mafia to undergo a full stadium tour later in the year, allowing for their own production and advertisement.

[64][65][66] Although not a scheduled tour date there were many rumours that Swedish House Mafia would close Tomorrowland 2019, especially after Steve Angello claimed in the Autumn of the previous year that the group would play at the festival "by any means necessary".

[67][68] As the festival drew closer no official announcement was made but the evidence suggesting a surprise performance grew even stronger with the group's signature "three dots" appearing on the Tomorrowland lineup.

[71][72] Despite this, British trance DJ Gareth Emery claimed that the group were to play the show in a statement about his Tomorrowland set, with him suggesting a disagreement over stage design was the reason for their supposed cancellation.
