For me THE reference disk Tommy Flanagan. There are the special class of its very inspired bop sentences (Confirmation), and the lesser known but ... wrongly themes! Maybe September is a beautifully melancholy ballad. The standard "How high the moon" is revisited in slow tempo, with swings that reaches ecstasy. George Mraz holds a key position, he played the themes and dialogue with Flanagan and the rest of the time it firmly supports.
