Swedish House Mafia

Swedish House Mafia are Axwell, Sebastian Ingrosso, and Steve Angello — three Swedish producers who built their sound around driving progressive and electro house, the kind of big-room electronic music that defined festival main stages in the early 2010s. Their 2012 single "Don't You Worry Child" reached the top of charts across Europe and became one of the decade's most-streamed dance tracks, and the trio reunited in 2018 after a five-year split that had been announced as a permanent goodbye. Their live format is a full production show built around light rigs and synchronized visuals, so the scale of the venue matters — a large indoor or outdoor space is where the set makes sense.
