Listen to Swedish House Mafia on iHeartRadio

Don't you worry children, Swedish House Mafia has finally released the official music video for their latest single, which is out today on iTunes. "Don't Your Worry Child" is an unforgettable progressive house song that features the chilling vocals of John Martin. Martin is a Swedish singer who was also the voice of another popular anthem of theirs "Save The World".

The video was shot at the trio's famed Milton Keynes Bowl show over the summer, where they made history as the biggest electronic dance music event in the UK this year, as well as the boys' last performance there. Talk about going out with a bang. The show was supported by some of the hottest names in electronic dance music currently, with sets from Calvin Harris, Alesso, Pete Tong, and more.

Giving the world an exclusive look at one of their biggest and greatest performances to date, the video not only features SHM (who arrived to the show in a helicopter!) going crazy behind the decks, but also focuses on their thousands upon thousands of enthusiastic and euphoric fans who packed out the venue. The performance is electrifying to watch, with the pyrotechnics, fireworks, confetti showers and mind-blowing lazer shows as the video goes from day to night. 

The video also features a special message from Axwell, Steve Angello, and Sebastian Ingrosso said during the show, "We've been waiting for this night. I would just never have pictured it like this. So thank you so much for coming down, and making this the best show of our life. Thank you!"
