What if you were given the keys to Blue Note Records' legendary tape vault? In 1975, that's exactly what happened to three-time Grammy Award winner Michael Cuscuna. There, the record producer and co-founder of Mosaic Records discovered hundreds of hours of unreleasedand undocumentedsessions, which he diligently pieced together before releasing. This sleuth work made him an expert on Blue Note, from label founder Alfred Lion's obsession with jazz in the 1920s to Blue Note's heyday in the 1950s and '60s to its recent success with Norah Jones.
