Soileau, France, is the site of the annual Nuits Cajun et Zydeco festival.  Here’s a very hot video with two songs, “Les flammes d’enfer” and the “Bosco stomp.”  The band is given as “Marais Bouleur,” and the members are Blake Miller-accordion & vocals, Yvette Landry-bass and Chris Segura-violin, accompanied by Jacques Boudreaux on guitar and vocals and Danny Devillier on drums.
