Yet, with all of Elmo’s fame, the man behind the icon is able to walk down the street without being recognized.

Interweaves the extraordinary story of Septentrional’s six decades of creativity with the history of Haiti. How did the country go from being the first free black republic with a huge wealth of natural resources to a shattered nation unable to support its citizens? How did the hope created by the rise of Jean Bertrand Aristide and the despair that followed the coup that drove him from power contribute to the inevitability of the January 2010 earthquake’s horrific death toll? The film gives context to the current problems facing Haiti, from the brutality of French colonialism and the bloody revolution that brought Haitians their freedom to the crushing foreign debt, the 15-year American occupation that ushered in the brutal dictatorship of “Papa Doc” Duvalier, and the earthquake that killed almost 300,000 people. The passion, commitment, dreams, and joy of Septentrional’s musicians reveal the indomitable Haitian spirit. With a sweeping narrative and infectious music, this is the story of not just one band’s survival, but also Haiti’s survival.
