Since opening a brick-and-mortar shop in 2015, Moscow’s Humble Burger has carved itself a niche for cool indie concerts in North Idaho. Last year, the restaurant launched Modest Music Fest, an event that’s in keeping with the restaurant’s non-ostentatious name, and it returns this weekend with a diverse lineup of live music taking over downtown Moscow. This year’s big headliners include rapper Lil B and Built to Spill frontman Doug Martsch, and amongst its stacked collection of mostly Pacific Northwest artists, there are a handful of Spokane acts — Itchy Kitty, Odyssey, Jango, Lavoy and Mama Doll.
