On his new album Youth., Kalle Mattson set out to make a coming-of-age album about the in-between days of post-adolescence and pre-adulthood. "It's about when dreams become your regrets, your friends become strangers, your first love becomes your first loss, & you become truly nostalgic for the first time," says the 27-year-old Ottawa songwriter, who grew up in Sault Ste. Marie, a small Northern Ontario border town between two Great Lakes. Sonically, Youth. is caught between worlds as well: the stark acoustic demos Mattson recorded in his bedroom, and the glossy electronics that producer Colin Munroe (Sky Ferreira, Kendrick Lamar) brought to the project. Mattson got a lot of international attention for his award-winning 2015 video "Avalanche," in which he inserted himself into his favourite album covers, but with Youth. he's become the star of his own show.
