Since banding together during the 1972 student uprising that toppled Madagascar’s neocolonial regime, the acclaimed folk-pop group Mahaleo has been performing and recording songs that reflect the aspirations of the Malagasy people. Their melodious, polyphonic tunes glide over vivid images of island life in this impressionistic 2005 documentary, which checks in with the seven band members as their 30th-anniversary concert approaches. The ideals of their socially progressive lyrics are reflected in their day jobs; hoping to move the country toward true independence, they’ve pursued careers in medicine, politics, and the nonprofit sector. Marie-Clemence Paes and Raymond Rajaonarivelo directed. In Malagasy and French with subtitles. 102 min.
