Brandee Younger has advanced the pioneering jazz contribution of harp predecessors like Alice Coltrane and Dorothy Ashby (whose “Afro-Harping” she covers), but since emerging in the 2010s, she has also spread her wings creatively, tapping into R&B, hip-hop, and free jazz. No harpist is better suited to adapting such a singular instrument to so many traditions. In a duo with her bass-playing husband, Dezron Douglas, she pulls lyric beauty and deep soul out of jazz and pop classics, while her band recordings nonchalantly summon the spiritual jazz sound of the '70s, sleek post-bop and classic funk.
