This may actually be a quite good collection which was originally collected for the Smithsonian's American Jazz Heritage in 1998 on a Sony Special Product label. Unfortunately, without more information about tracks or artists, it is impossible to know for sure. IF it is the same collection, you should buy it in a hearbeat--it's a complex, comprehensive, and frankly stunning survey of the American jazz vocalist from 1919 to the mid '90's. The enclosed booklet with incredible detail on the background and musicians of each track is an education all by itself.If not...well, "Armstrong, et al" is not a lot of information to base your purchase on (great as Satchmo is).
