The music of Nick Waterhouse sounds like it was beamed straight from 1961, drawing heavily on doo-wop, rockabilly, rhythm and blues, and jazz, with heavy dashes of modern blue-eyed soul. “Katchi,” featuring guest Leon Bridges, is studded with some charming, deep-timbered “Doo-wop a doo-wop, shoopi doobi doo-wops," and a fun, catchy hook using a word Bridges’s family uses for a nice massage or a loving touch. (In this context, they’re obviously howling about sex—“She give me katchi all night long”—a nod to the vintage style of using double entendre and innuendo.) The guitarist and singer-songwriter is currently on tour behind his eponymous fourth LP. by Leilani Polk
