People Editorial Guidelines Published on April 24, 2018 10:05 AM Share Tweet Pin Email Despite his success on the charts, Avicii wasn’t comfortable with the celebrity lifestyle. “He was totally thrown into this. All he wanted was to make beautiful music,” deejay Laidback Luke — who mentored the late musician (born Tim Bergling) when he was a teen — tells PEOPLE. “2015 was the last time I saw him face to face, and I remember there wasn’t much Tim left. Tim looked to me kind of like a zombie. He had aged significantly. When I saw him perform, it was as if he wasn’t in touch with life anymore.” Another friend describes Avicii — who was found dead at 28 years old on Friday in Oman — as the “nicest, most generous and hardworking guy” who had a deep “passion for creating music.” “He was extremely talented. He was always very honest about how he hated being a celebrity,” says the pal, who first befriended Avicii in the early years of his success. “It was very difficult for him emotionally. He was never comfortable being in a social spotlight.” Avicii’s Body Will Be Flown Home to Sweden This Week: His Family ‘Are All Completely Devastated’ Johnny Nunez/WireImage Indeed, another source close to the late entertainer explains that “Tim was Avicii, but Avicii was never Tim. He was sweet, sensitive and like a guy that didn’t want to be at the party, let alone the reason people were there.” “Parties, the scene, leeches instead of friends … it was all too much for his sensitive soul,” continues the source. “He wanted to watch movies all night, not party all night. It’s like he didn’t know who he was without his career, but his career was killing him — literally.” Laidback Luke first met Avicii when he was just 16 years old, and the producer was especially impressed by his protégé’s work ethic. “The Tim I knew was very eager, very excited. He just wanted someone to hear his music,” says Laidback Luke. “I was quite strict on him trying to give him proper direction and the right production tips. He was always very open to critique and eager to improve himself. It became quite clear he was really good with melodies and coming up with these little packages of emotions regarding his music.” Prior to his death, the star retired from touring in 2016, after having spent years pushing himself through a grueling workload and suffering from ongoing health problems, including acute pancreatitis, an inflammation of the pancreas that doctors attributed to heavy drinking.

But say you have an anxiety for snakes or are scared of heights and every single night you need to jump off a building, or every single night you need to face a room with snakes. You can see how that could influence someone’s health.” Avicii previously admitted to GQ that he drank as a way to cope with his anxiety. “I just got into a habit, because you rely on that encouragement and self-confidence you get from alcohol, and then you get dependent on it,” he told the publication in 2013.

He was extremely generous in so many ways.” “It’s incredibly sad that he is gone. His family is still in shock,” the insider adds.
