The funeral of the Swedish DJ and music producer Avicii, one of the biggest stars in electronic dance music, took place in a private ceremony in Stockholm last week, his publicist has said.

The musician, whose real name was Tim Bergling, “was buried [on] Friday at the Skogskyrkogården cemetery in Stockholm”, Ebba Lindqvist said on Tuesday. “Only his family and closest friends were present.”

Avicii, 28, was found dead on 20 April in Muscat, Oman, where he had been on holiday with friends.

Omani police said no evidence of foul play had been found. The cause of death has not been announced.

In an open letter published several days after his death, the DJ’s family said he “wanted peace” and “could not go on any longer”. “He really struggled with thoughts about meaning, life, happiness,” they wrote.

Avicii, who collaborated with Madonna and Coldplay, was one of the first DJs to break into the mainstream, with the hit songs Wake Me Up and Levels, as electronic dance music spread over the past decade from nightclubs to top 40 radio.
