“Propagation” is a single from Lower Dens’ forthcoming album, “Nootropics”, out May 1st in North America and April 30th for the rest of the world on Ribbon Music. It’s a smokey twilight song, with a tangle of echoed backing vocals, lead vocals, and contemplative atmospheric guitar. A real beauty. You can pre-order “Nootropics” on limited-edition gold-colored double LP with black swirl here. — David D. Robbins Jr.
