This is the latest reissue from Blue Note, the most influential jazz label in history, on the occasion of its 85th anniversary. The latest remastering was done by Kevin Gray, a sound engineer who also acted as master for Blue Note's analog reissues in the US such as "Tone Poet" and "Classic Vinyl". By using the digital source material he created for the analog reissues, he was able to reproduce the sound of the original master tapes as faithfully as possible, achieving the ultimate analog sound. In UHQCD format. *UHQCD (Ultimate High Quality CD) is an improved version of HQCD, a Hi-Fi CD format developed by Memory-Tech. Uses the 2023 remaster.
