Natacha Atlas has changed direction again. In her days with Transglobal Underground she mixed furious Arabic pop, beats and belly-dancing, then switched to acoustic styles with the subtle and magnificent Ana Hina. Her last album, Mounqaliba, was languid and forgettable, but here's another reminder of what an exquisite singer she can be. She's a major star in France, but it was still a brave move for her and her band to record live with the Toulouse Chamber Orchestra, especially as the set includes several new songs. They open with Rise To Freedom, an easy-going "salute to the 2011 Egyptian revolution" in which piano and strings are matched against hand percussion, but she's at her best with Fayeq Walla Nassi, a slinky and charming tribute to the Lebanese legend Fairuz, while the cool, North African/jazzy treatment of Nick Drake's Riverman is far more compelling than her studio version.
