Boca do Rio will bring its Brazilian Space funk to Alibi Ale Works – Truckee Public House at 9 p.m. Saturday, Dec. 8. Free show. An Afro-Brazilian World music group from Northern California, Boco do Rio delivers a unique blend of pop hooks, pleasing vocal harmonies, funky rhythms, and African percussion with contemporary beats on its EP “The Dam is Breaking.” The result is joyously melodic and uplifting, with the contemporary accessibility of the Rippingtons and the depth of Stan Getz’s “The Girl from Ipanema” and the Brazilian bossa nova from years past. Boca do Rio (Portuguese for “mouth of the river”) strikes the perfect balance between delicate smoothness and energetic edginess, resulting in vibrant, vast landscapes of sound. Rooted in distinct instruments that seem both timeless and yet also grounded in the here and now, “The Dam is Breaking” is full of energy, passion, vitality and life. Possessing an urgent environmental message, every song is impeccably written, arranged and performed, resulting in an EP that is superbly crafted and expertly produced.
