The trio formed during the mid-2000s whilst touring together and assisting each other in music production,[1] and released the single "Leave the World Behind" in 2009, although all were assigned individual artist credits for the song.

[2] The group itself rose to prominence after performing a DJ set at the Cream Amnesia nightclub in Ibiza in 2008, and were later signed by record label EMI in 2010.

[6][7][8][9] "One" and "Miami 2 Ibiza" were certified septuple and quintuple platinum in Sweden by the International Federation of the Phonographic Industry (IFPI).

[4][13] Four singles were released from Until Now: "Save the World", "Antidote" – a collaboration with Australian electro house group Knife Party – "Greyhound" and "Don't You Worry Child", with the latter proving to be the most successful: it became their first song to peak at number one in Sweden,[4] and also topped the ARIA Chart and UK Singles Chart.

Swedish House Mafia reunited in 2018 and their debut album, Paradise Again,[15] was released on 15 April 2022.
