75 tracks on 5 CDs. No real info (other than Cassandra Wilson and Norah Jones are on Disc 4) This is the puffery: Each of the five discs covers a specific era, from boogie to hard bop, soul jazz to the roots revival of the 90's, and the 21st century trailblazers like Robert Glasper and Gregory Porter. Not interested in this or the Monk. I'm so done with buying the same material over and over. Me too!
