Grouper's Liz Harris is certainly keeping herself busy these days with wide array of side projects and collaborations. Her latest is an effort with Jefre Cantu-Ledesma called Raum. A gorgeous array of looped and echoed vocals, feedback, fuzz, and wonderful humming drone, the music sounds like sinking into the carpet of your bedroom...but in a good way. "Blood Moon" is out next week on Glass, house. Listen to the title track below.
