Swedish House Mafia is a Swedish electronic dance music trio consisting of three house disc jockeys and producers, Axwell, Steve Angello, and Sebastian Ingrosso. The group officially formed in late 2008. The supergroup placed at number ten on the DJ Magazine Top 100 DJ Poll 2011. On June 24, 2012, the group announced via their website that their current tour would be their last together before a hiatus. In 2012, Swedish House Mafia won an EBBA Award.

Every year the European Border Breakers Awards (EBBA) recognize the success of ten emerging artists or groups who reached audiences outside their own countries with their first internationally released album in the past year. Angello and Ingrosso met as children in Stockholm; Axwell did not become a member until years later when they contacted him after a chance meeting.

The first production that was released by Axwell, Steve Angello and Sebastian Ingrosso was "Get Dumb". It was produced with Laidback Luke and released in 2007.

In 2009, they released "Leave The World Behind" with Laidback Luke and Deborah Cox and in 2010, Swedish House Mafia signed a record deal with UMG's Polydor Records (formerly Polygram) after a fallout from previous record label EMI, due to differing ideas. They released their first official single, "One (Your Name)", under the name Swedish House Mafia on Beatport on May 26, 2010, where it achieved international success, charting at number 7 in the UK Singles Chart.

The next single, "Miami 2 Ibiza", featuring Tinie Tempah, charted at number 4 in the UK Chart in September 2010. Both tracks were taken from the album Until One; a collection of productions and remixes from both Swedish House Mafia as a group and as individuals.

It has achieved a BPI Gold Sales award in the United Kingdom. In May 2011, Swedish House Mafia released a new single, "Save The World," featuring John Martin on vocals, which charted at number 10 in the UK Chart.

Later that year on December 16, they released the track "Antidote" with Knife Party. On March 12, 2012, Swedish House Mafia released their next single titled "Greyhound" and their final track "Don't You Worry Child" was released on September 14, 2012.

That same month on September 17, the group announced the release of a second compilation album titled Until Now, forming the official soundtrack to One Last Tour. The album was released on October 19, 2012, two years after the release of their first compilation album Until One.
