Julianna Barwick + Mas Ysa + Mankind + fantasy league + Nathan Phillips

This Brooklynite singer and composer uses effects pedals to loop her voice, piano and other sounds into dense, shimmering clouds of audible color. Singer-producer Thomas Arsenault a.k.a. Mas Ysa—who's featured on the penultimate track of Barwick's most recent album Will—takes the opening slot. Usually, he's known for his earnest, confessional pumping indie pop delivered through a paper-thin croon, but here he performs a special ambient set.
