Julianna Barwick & Mary Lattimore

This is the collaboration that ambient music fans have been waiting for. Julianna Barwick builds cathedrals out of looped vocals—layered, ethereal, drawing on her years in church choirs. Mary Lattimore is a harpist who's worked with everyone from Kurt Vile to Thurston Moore, pushing her instrument into places it's never been. They've been friends for years, toured together, collaborated on tracks like "Oh, Memory" from Barwick's Healing Is A Miracle. But Tragic Magic, released January 16, is their first proper album together.

They made it in nine days at the Philharmonie de Paris, with access to the Musée de la Musique's instrument collection: an 1873 Érard double-movement harp, a 1728 Jacob Hochbrücker harp, a Roland Jupiter, a Sequential Circuits Prophet-5. Trevor Spencer (Fleet Foxes, Beach House) co-produced. The result is what Pitchfork called "avant-pop unlike anything else"—baroque textures, sci-fi synths, and the "musical telepathy" of two artists who know exactly when to leave space.

GAMH's high ceilings and natural reverb will serve this music well. Don't expect a rock show; expect immersion. Bring someone you want to sit in comfortable silence with afterward.
