One of the world’s most successful DJs, Avicci, died on Friday, April 20, in Oman. He was 28.

Two years after his unusually early retirement from touring, the Swedish DJ was found dead in the Gulf sultanate’s capital Muscat.

“It is with profound sorrow that we announce the loss of Tim Bergling, also known as Avicii,” his management said without giving hints on how the DJ had passed away or why he was in Oman.

“The family is devastated and we ask everyone to please respect their need for privacy in this difficult time. No further statements will be given.”

In fact, Avicii had won two MTV Music Awards including a Billboard Music Award and two Grammy nomination for his popular hit “Le7els”.

Avicii was among the first DJs to break through in the mainstream as electronic dance music grew over the past decade from nightclubs to Top 40 radio. He created a global hit out of Coldplay’s “A Sky Full of Stars,” to which he added a layer of energetic electronica.

He also helped produce Madonna’s last album. On Instagram, the pop superstar posted a picture of herself in the DJ booth with Avicii and wrote, “So tragic. Goodbye dear sweet Tim. Gone too soon.”
