I saw this girl open for Esben & The Witch at the Tractor quite a while ago. It feels weird to call her the opener when it didn't even feel like a show to begin with. It was more like hanging out in your friends living room where some chick with a looping machine happened to be singing. The tiny crowd was silenced once she started layering upon layering her own voice. You could easily put her in categories with Austra & Zola Jesus but there's something more angelic about her that them.
Check out this remix I just found.
