This lively documentary takes the viewer deep into the Cajun and Zydeco musical world of Louisiana, and features interviews and performances from some of the best known musicians, as it traces the history of both musical forms using archival footage from the 1930s onward. That history is inextricably intertwined with the history of the people who settled Louisiana, and the documentary illuminates that story with interviews from historians and folklore specialists. Among the many musicians featured are Clifton Chenier, Queen Ida, and Wayne Toups. These two musical forms were almost obliterated by the influx of U.S. popular music when rural Louisiana became less isolated after World War Two, but they underwent a revival in the 1960's which has continued to this day.
