Listening to Julianna Barwick. If you've ever wondered what the female version of Cathedral Oceans would sound like, try this. She apparently makes most of her music using her own voice, running it through guitar effects pedals and looping it. Most of the vocals are wordless ooh and ahh sounds, treating her voice more as an instrument for a result somewhere between Cocteau Twins ethereality (replacing Guthrie's guitars with vocal loops) and ambient. At least on the couple of tracks I've heard so far.
