Jinsang, a new producer based in California, specializes in pastoral boom-bap. The root cause may well be Nujabes’s “Aruarian Dance,” which he remixed in 2015. With its central, gentle melody derived from 19th-century impressionism, this 2004 Samurai Champloo instrumental literally has timeless appeal. Jinsang adds percussion, plus a scene from the anime itself, but otherwise keeps the heart of “Aruarian Dance” intact. It is a sweet, simple gesture for anyone who wants to feel less alone when they’re missing the late producer.
