To a sultry and dangerous blues crawl, Boston’s Abigail Ory enters, drenched in a hot and sticky passion few times encountered in music and elsewhere: the singer/songwriter’s latest single “Waves” is a milky sonic sea to bathe in. The heart-beat bass, the fuzzy electric guitar strums, and Ory’s velvety vocals all ignite the unison shifts that give life and edge to the track, fit for the most underground of clubs, for the best places to catch an evening-altering song. In “Waves,” Ory shows, at a young age, a maturity that separates her from the current crop of indie-pop artists, selecting with care influences beyond the available palette. Stream “Waves” below for a dramatic exit from the week, for a fiery entrance into the weekend. - Rene Cobar
