Pitchfork Music Festival 2015: Mourn

None of the members of this Spanish group are old enough to drink (in the States) yet, but they're already headlining their own Pitchfork aftershow. Drawing inspiration from PJ Harvey and Sleater Kinney, Mourn's self-titled debut harnesses the groups youthful energy, evident on tracks like "Your Brain is Made of Candy" and "Boys are Cunts."
