Swedish House Mafia is a Swedish house music group consisting of the three disc jockeys and producers, Axwell, Steve Angello, and Sebastian Ingrosso. The group officially formed in late 2008.
Angello & Ingrosso met as children in Stockholm; Axwell was not 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 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 26 May 2010, where it achieved international success, charting at number 7 in the UK Singles Chart.
