Two-time Grammy winner Louisiana’s BeauSoleil has been the very heartbeat of Cajun music and culture, keeping it vital through not only their attention to tradition, but also through passionate and inventive experimentation. On Evangeline Waltz the ensemble finds freshness not by infusing vintage styles with contemporary sonics but with vibrant, thoughtful fusions. Now in its 47th year, BeauSoleil manages to shine as both a dance band and a concert act. On this limited edition 2-CD package, the band performs to a “small living room” audience in their hometown. “It was a magical night,” band leader Michael Doucet says.
