Grimsøn is a music and animation project.

After beginning in New York’s underground scene, 22 year old Swedish/American songwriter 

Aiden Berglund made his way to Berlin in the midst of the pandemic and began recording as Grimson, shifting his style into Burton-esque Gothic rock accompanied by sweet harmonies and baroque pop arrangements. Grimson found an audience on Tiktok for his dark humor and challenging yet radio-ready singles, which has amassed over a million streams and views on his songs, animations, and viral videos. He incorporates an intricate multimedia element into the world of his songs, pulling from his work as a character designer and animator, which includes the video for Weyes Blood’s “It’s Not Just Me, It’s Everybody” and visuals for Jose Gonzales, Sharon Van Etten, and more. In 2024, Grimson supported other major Tiktok artist and chamber pop bastion ROAR on their European tour, securely cementing Grimson’s already strong appeal to young and wildly enthusiastic fans. For his bombastic live set, Aiden enlists help from Berlin-based and highly sought-after UK and Irish session musicians who have worked with Gang of Four, Tricky, James McCartney and more. Aiden is currently teasing tracks such as “I Made My Therapist Cry Today” (from his upcoming album) on social media, and further building out the animated universe of Grimson. Grimson is managed by Sam Spacassi from We Are Free (Weyes Blood, Beach House) and is currently independent.
