In Memory of Mattheis: Support His Family

On July 10, our community was shaken by the heartbreaking loss of 15-year-old Mattheis, who passed away in a tragic accident after an outdoor pop-up concert at Gas Works Park.

Mattheis was a bright, blossoming soul—an artist, musician, and friend to many. Though he may have seemed shy at first, those who knew him best saw that he lived with incredible vibrance.

Many described him as having an old soul. He sang, produced his own music on Spotify, loved deep conversations, fashion, ran track, and played ultimate frisbee for Ballard High School. He was constantly making new friends and was never afraid to show a sweet, open-hearted love for his mom—even in public. He was often seen walking his dog with his dad and/or younger brother, just being present in the world around him.

His friends remember him as someone who never spoke an unkind word, made people laugh, and who inspired others simply by being himself. On the morning of this tragic accident, Mattheis released a teaser track for his upcoming second album—a project he had poured his heart into (LINK HERE).
