Friends, family members, fans and celebrity admirers are paying tribute to Tim Bergling one year after he was found dead in Muscat, Oman.

The Swedish DJ and music producer, better known as Avicii, is believed to have committed suicide. He was 28 years old, and was one of electronic dance music's most promising rising stars.

It was on April 20, 2018, and fans had described him as "full of life" in the hours that led up to his death. At the time, his family issued a statement saying that he had struggled with life and "could not go on any longer".

Most recently, his family launched the Tim Bergling Foundation, aiming to raise money and awareness for a variety of causes, starting with those related to mental health and suicide prevention. But they also hope to tackle hot-topic issues such as climate change, endangered species and nature conservation, too, in Avicii's home country as well as overseas.

Earlier this month, they also announced they would be releasing a posthumous album of Avicii's music, called Tim, which he was working on before his death. The single, SOS, dropped on April 10. Profits from the album, which features Coldplay singer Chris Martin and is co-produced by many of the artist's long-time collaborators, including Albin Nedler, will go directly to the new foundation.

Anniversary tributes

People have taken to social media to express their sadness one year after the Hey Brother star's death. Fans are posting under the hashtag #AviciiForever.

"It's one year since one of the greatest artists that have ever lived left this world," wrote one fan on Twitter. "You and your songs will always have a special place in my heart."

"We lost you and you helped keep me here," wrote another user, while showing off their Avicii tattoo. "I wish I could have thanked you in person."

Friends and collaborators also shared their favourite memories of the star with New York radio station SiriusXM. “My earliest memories were him just being very curious about the world,” Malik Adunni, Avicii’s tour manager, said.

Referring to Avicii's reserved character, Adunni added that “when he got on the stage, that’s when the shyness would go away because he would get the energy from the crowd.”

Dutch DJ Nicky Romero recalled the moment Avicii played Wake Me Up for the first time. “He broke the barrier there and made it a hit. He educated people with something new, and that’s something I appreciate and respect a lot. I’ll never forget that moment.”

Carnage, a DJ and friend of Avicii's, who collaborated with him on Waiting for Love, said, “What he accomplished so young motivated me to go harder and to go stronger. The relationship that we had was just true. We had some of the best times together.”
