The way Florist comes on is so quiet and unassuming, you might wonder if the band is actually playing music. That is, of course, until it’s obvious that they are, and that the rain and breeze and crickets that so unassumingly complement their songs aren’t just accessories but foundational: This is music about rivers that wants to make you pay more attention to rivers. Some songs stand out—“Red Bird Pt. 2,” “Sci - Fi Silence,” “Spring in Hours,” “Organ’s Drone”—but they’re best absorbed in the same casual, front-porch mode in which it sounds like the music was made, and through which vocalist Emily Sprague’s naive wisdom transmits.
