Swedish DJ Avicii, who has collaborated with the likes of Madonna and Coldplay, has died in Oman at the age of 28.

Avicii's club anthems include Wake Me Up, Hey Brother, and recently, Lonely Together with Rita Ora.

His representative said in a statement: "It is with profound sorrow that we announce the loss of Tim Bergling, also known as Avicii.

"The family is devastated and we ask everyone to please respect their need for privacy in this difficult time."

No cause of death was announced, and Avicii's representative said no further statements would be issued.

Avicii had struggled with some health issues in the past, having his gall bladder and appendix removed in 2014.

He announced his retirement from touring in 2016, partly because of the health problems.

"I know I am blessed to be able to travel all around the world and perform, but I have too little left for the life of a real person behind the artist," he said at the time.

He later announced a return to the studio and released a new self-titled EP in 2017.

The EP, Avĩci (01), was nominated for a Billboard music award for top electronic album just days before his death.

Other leading electronic artists wrote tributes to Bergling after the news of his death.

Tributes

Singer Dua Lipa tweeted: "Such sad news to hear about Avicii passing. Too young and way too soon. My condolences go out to his family, friends and fans."

US band Imagine Dragons tweeted: "Working with him was one of my favourite collaborative moments. Far too young. The world was a happier and fuller place with his presence and art."

"No words can describe the sadness I'm feeling right now, hearing about Avicii passing away," offered DJ Zedd, while singer Adam Lambert, who collaborated on the track Lay Me Down, called him "a brilliant composer and a gentle spirit."

An enchanting artist

At Avicii's last ever show in August 2016, one crazed fan climbed a 100ft-high (30m) scaffolding tower, just to get a better view.

That's not something that happens that often during a DJ set (who needs to see the stage anyway?) but it was a testament to Avicii's ability to enchant an audience.

Confetti cannons and bass drops aside, his shows encapsulated the inclusive, everyone-welcome philosophy that led him to collaborate with Coldplay, Nile Rodgers and Antony Hegarty as well as bluegrass and metal musicians in the studio.

That final show, at Ushuaia Ibiza, was a two-hour greatest hits set, featuring crowd pleasers like Levels and Wake Me Up alongside his remixes of Robyn and Dizzee Rascal.

But the DJ, who famously let the cat out of the bag when he revealed most major DJs pre-programmed their sets (comments he later walked back), was also known for dropping unexpected, whimsical tracks into his performances. A bit of Smokey Robinson here; a dash of Chicago there.

He approached it all with an energy and optimism that permeated his own recordings. It's no surprise he was one of the most beloved DJs on the circuit.
