This Washington duo have kept the flame of trip-hop alive since the late 1990s, sometimes extending into psych and dub, always mixing in “world” elements. Here, they take a leftfield turn with an album of hushed bossa nova reflecting saudade, or longing. They take a surprisingly organic approach, tweaking bossa’s twitchy guitar rhythms with shimmering backdrops and the odd electro beat. Five classy female vocalists provide a sensuous lilt to songs delivered in Portuguese, French and English., and the odd plunge into cheesecore, like No More Disguise, doesn’t mar an album perfect for late-night Brazilian campfires this summer. Sumptuous.
