On Saturday, the Hall Band will be the focus of Louisiana Fairytale, a documentary by Danny Clinch that will show at the Ogden Museum of Southern Art. It focuses on the relationship between Preservation Hall and rock band My Morning Jacket, and it takes its name from the song that My Morning Jacket’s front man Jim James (AKA Yim Yames) performed with the band for its 2010 album, Preservation.

The film is a behind-the-scenes look at the unlikely integration of two bands, one dedicated to the conservation and advancement of traditional New Orleans jazz, the other focused on breaking down the barriers of the rock genre and exploring new worlds of music. The hour-long film features the bands performing in the famously intimate Preservation Hall.
