‘Filmmaker Sascha Just’s mastery of form is on clear display in this documentary. The title of this subtle, expertly assembled inquiry into the lives of two contemporaneous Black Creole classical musicians from New Orleans is telling: When it comes to both brilliant New Orleans native sons, the scarcity of archival traces means there’s not too much we can know about Edmond Dédé and Basile Barès definitively. It is to Juste’s credit that she leans into the mystery—showing the racial motivations behind their erasure while also answering her own question in unexpected ways. The main characters of the film, besides the titular musical ghosts, are contemporary New Orleanians who answer to the challenge of resurrecting their music and search doggedly through the archives to find everything they can. There is a man who fixes old pianos, including those owned and distributed by Barès, and Oscar Rossignoli, the New Orleans piano virtuoso who performs Barès pieces at Sung Harbor.‘
