Fellow star DJ Kygo took to the main stage on Friday night and ended his set with an emotional tribute to Avicii.
"Coachella, I think most of you guys have heard but today is a very sad day for music. Earlier today I got the news that Avicii passed away only 28 years old. Avicii was my biggest musical inspiration and he was the reason I started making electronic music so I don't think I would've been on this stage tonight if it wasn't for him. I know he's inspired millions of other producers out there. So I want to end my set tonight with my favourite Avicii song," Kygo said, before he closed his performance by playing Avicii's 2017 single, Without You.
"In honour of Avicii I want you to dance and sing along and let's celebrate the life of a true musical genius," he added.
