It is a question of an album that is part of the history of jazz and which perhaps we were told little or nothing about. That is why I don 't will add other than the fact that this edition I just select and purchase (re-mastered Columbia / Sony / Legacy 2009) offers a great sound quality and an "alternate take "of" Flamenco Sketches "not present in the original album. Nice little booklet inside with beautiful photos, information about the musicians and the production and the image of the LP B façade of the time .. Current price very interesting for all sellers. Enjoy Miles ..... !! And Bill and John and Cannonball ...
