about summersets

summersets is the new duo from Juno and Polaris nominated singer-songwriter Kalle Mattson, and longtime collaborator Andrew Sowka. Influenced by the storytelling of John Prine and delivered with the delicacy of Simon & Garfunkel, their debut full-length, 'small town story', was produced by Jim Bryson (Kathleen Edwards, The Weakerthans) and nominated for both a 2024 Ontario Folk Music Award and a 2025 Canadian Folk Music Award. They are currently in the studio working on their followup LP once again with Jim Bryson, Peter Von Althen (Skydiggerrs) and Christine Bougie (Bahamas), due in 2026.
