He left back in 2020, he had a baby and needed to spend more time with his family. Here's the official statement "Ladies and gentlemen, Here’s a sad piece of news. Magnus aka Magnúm will no longer be a touring member of Lukas Graham. This decision comes after a few months of careful consideration on Magnus’ behalf. He is so lucky to have his first child on the way and he has decided to spend his time and energy close to home with his growing family. The unforeseeable workload and time pressure as an international musician can sometimes feel insurmountable and it can be hard to create a healthy work/life balance. It’s this imbalance that has made Magnus decide to leave the band after due consideration. Magnus will always be a part of the family in and around Lukas Graham and I look forward to see what creative roll he might have to play in the future. Cheers to 10 amazing years together. Thank you Magnus for a wonderful time 💚"
