When listening to Julianna Barwick’s music, especially her excellent 2013 album, Nepenthe, it’s easy to forget that nearly everything you’re hearing comes from her voice, impressionistically looped and layered. Fortunately the Louisiana-born, Missouri-raised, and Brooklyn-based experimental siren’s live shows get that across as she builds glacial and blissful songs right in front of you. Barwick recently shot a live session at the Andy Warhol Museum in New York City, and you can watch her perform one of her best songs, “The Harbinger,” from that below. If you’re in the NYC area catch her tomorrow night performing with the Brooklyn Youth Chorus at Roulette.

In other news, Barwick’s Rosabi EP is out this week (via Dead Oceans) in conjunction with the beer she made with Dogfish Head.
