On her fourth album, the Welsh singer Cate Le Bon establishes a strange, almost Dadaist lyrical scheme to make sense of some unnamed life rupture that's left her gasping.

Crab Day is a voyage into doubt led by a queasy compass, and a ringleader who's prepared to stake out uncertain territory. Le Bon always keeps you guessing, making the old traditions of guitar-oriented rock feel arbitrary, too. Her nervy assessments of the world are filled with equal parts suspense and heart, and beautifully zany riffs, where the feeling of being frayed by uncertainty comes together into a strangely comforting patchwork.
