Julianna Barwick, and I'm totally glad we were there. Her set was ethereal, captivating and so very cool. I don't know the specifics of it, but she sings into something that keeps looping her voice until it sounds like you're listening to a heavenly choir. Believe me, it sounds much, much better than my description of it. Although the music is mainly driven by her voice, but there is some instrumentation to be found. Her album is called The Magic Place, and it more than lives up to that title.
