On Beautiful and Strange, which follows 2017’s Boomerang, Williams and her producer (and husband) Ross Garren, somehow strike a wire-walker’s balance between the seemingly opposing forces of childlike whimsy and mature sophistication. The former manifests as toy pianos, singing saws and a general lightness of being that floats like a breeze throughout these 11 tracks. The latter permeates their sweeping, deeply-layered arrangements, as well as Williams’ engaging style, whether she’s dissecting relationship dynamics or examining the very notion of destiny.
