Drone music is difficult to make-and keep-captivating. But it’s something that Coastal achieves in its best moments, notably the delicate eight minutes that open “Palmetto,” where a shimmering mid-tone and a low, oscillating pulse play tag with silence. But Daniell-who plays with Tim Barnes, Thurston Moore, and many other “out” music greats-really shines when he pulls out the acoustic guitar. On “Sunfish,” he riffs and loops into thick psychedelia, then leaps into soulful, bent notes, while on “Glasswort,” a little blues guitar turns dark dirges and rustling into a song you can follow.
