content: If one wanted proof that Art Tatum was the greatest (and I for one don't) this album would be Exhibit A. Tatum sits down at the keyboard before an enthusiastic audience at the Crescendo Club, and the excitement begins.From the first bars his genius is proclaimed. Song after song of creative improvisation flows from his fingertips. He is endlessly inventive in his unique melodic style,never repeating an idea or phrase from beginning to end.This recording illustrates that what was impossible for other pianists was effortless for Tatum,even in a live performance.Listening to masterpiece follow masterpiece, one has the impression that Art could continue improvising all night,weaving his polyphonic magic in a succession of brilliancies. My only complaint is that the date of the recording is not given.From the focused and comtemplative style, I would guess the early 50's.
