The milestone Madison Square Garden event will see Swedish House Mafia - Axwell, Steve Angello and Sebastian Ingrosso - make history by becoming the first dance act to headline the iconic venue, as well as recognition as one of the fastest sellouts at Madison Square Garden this year. These highly anticipated New York City performances will be the capstone to a phenomenal year for the Swedes, in which they attained two #1 Billboard dance hits (for ‘Save The World’ and ‘Miami 2 Ibiza’ feat. Tinie Tempah), a Grammy nomination for Best Dance Recording, and headlined massive events at Electric Daisy Carnival Las Vegas and Miami Music Week. Swedish House Mafia will also be releasing their new single ‘Antidote’ on 12/16/11. The track is a collaboration with Knife Party (side project for two members of Pendulum, Rob Swire and Gareth McGrillen) and treads a much darker path than the Swede’s usual productions and comes with a massive dubstep-esque warbling bottom-end.
