For his second album, Abdelli, an Algerian singer-mandola (a type of oud-lute) virtuoso from the Kabyl (an ancient Berber tribal group), has again pre-recorded his blues-inflected, slightly world-weary tenor vocals and some rhythm guide tracks before sending them to collaborators around the world to have their way with. Producer Thierry Van Roy kept everybody else in the dark until the final mix was assembled. Harp-like Andean guitars, piercing woodwinds, accordions, and assorted fiddles weave in and out, bringing with them dauntingly diverse sounds from the Andes, Africa, and the Arab world, as well as echoes of assorted medieval European styles (some of which originated in the Middle East anyway), Algerian Raï, and the Silk Road. Given the piecemeal nature of the production, the almost entirely acoustic arrangements are astonishingly organic and warm, robustly engaged but also airy and spacious. Even longtime band-mates performing face-to-face seldom achieve such a combination of unity and fearless individuality. -- Christina Roden
