This week on Transmissions: Joe Rainey. Rainey is a powwow singer of the Red Lake Ojibwe tribe. He’s known for collaborations with Bon Iver, Chance the Rapper and Alan Sparhawk of Low, and in May he released his debut solo album, Niineta on Justin Vernon’s 37d03d label. Created in conjunction with producer Andrew Broder, it pairs his vocals with samples culled from his vast collection of powwow tapes, thundering percussion, and dense, thickly layered soundscapes that evoke the overwhelming haze of modern electronic music.
