Very good value for the price
This compilation will be of great interest for both jazz discoverers or collectors since it provides a well balanced collection of reference works (Kind of blue, Concert by the sea, Lady in Satin) and less know (to me!) recordings (Helen Merril, Solal at Newport, ...).
Considering the quality of the box (booklet with full informations, facsimile carboard sleeves, ...) and the reduced price, it is a recommandable offer, even of you already have a part of it.
