Matt Halvorson is a Seattle-based musician and writer, and his music is released under the name Cousin Wolf. Imagine the back of a baseball card that makes you cry. Imagine laughing loudly and unexpectedly with your sisters. Imagine really putting your foot down and standing up to the System. It sounds like that.

Matt founded the Rise Up Music Project in 2019 as an excuse to write and record a song a week for a year, and he released the albums “Sermons” and “Winter” in 2020. On Opening Day 2025 he put out “Nine Innings,” a long-awaited passion project about life as understood through baseball. That was followed later in the year by the “Spring” EP.

For several years, Matt wrote and managed a blog called advocating for racial equity and radical empathy in our schools called Rise Up for Students. His first musical imprint was with the Portland-based folk-pop family band The Big Ideas.

Matt was born in Minnesota, grew up in the Dakotas and nowadays lives in a forest north of Seattle with his family. When not shout-singing at the piano or obsessing over lyrics, Matt enjoys coffee, campfires, fielding groundballs, and plotting to bring down the System.
