Saturday Morning Empires is a lovely compilation of slow-glazed electronics from Montreal’s Intr_version. Loscil’s “The Grid” has clear edges beset with icy chimes, like a brightly brittle morning after a storm-its hard, pure glint gives way to a simple guitar motif with a steady, subtly glitchy pulse. Ghislain Poirier’s “300,000 Engants Soldats” contains all the stillness and sadness of a curl of steam rising from a teacup, and the Polmo Polpo track is a dream drift propelled by chipper guitar plucks. Meanwhile, Tim Hecker haunts the edges of the album with tr»s filtered guitar creep.
