While Tribalistas evokes intimidating images of tribal fighters, this trio of Brazilian musicians—Marisa Monte, Carlinhos Brown and Arnaldo Antunes—is more akin to three kids creating a secret club to steal away and hide in the woods. In other words, this album is all about playfulness. Despite the informal feel, they toss off tuneful songs many would aspire to. Knowing Monte recently gave birth, it’s hard not to hear the influence of new motherhood; several tunes are soft and dreamy as lullabies. On “Mary Cristo,” the song even begins with the sound of a music box being wound up. The “trio-ing” of these disparate musical personalities works well: Monte’s gentle way balances Antunes’ quirkiness and Brown’s frenetic energy. If there ever is a follow-up to this sweet pop confection, it will undoubtedly be down the road, but this album serves as reminder of their amiable partnership and musical chemistry.
