This boxed set is full of incredible gems by Powell with many other giants of jazz (Cootie Williams, Dexter Gordon, Sarah Vaughan, Charlie Parker, Sonny Stit, Fats Navarro, Max Roach, Sonny Rollins, Roy Haynes, Art Blakey, Buddy Rich, etc.). There are cuts on this collection, especially on CD#4, that are up there with the best piano playing I have ever heard (that from a listener, not a player). My collection includes many great piano players - Evans, Tatum, Hines, Wilson, Peterson, Tyner, Garner, Brubeck and many others, but listening to this cd along with the Blue Note Best of Bud Powell (which picks up where Tempus Fugue-It leaves off - acting as a fifth CD in the set) convinces me that Powell ranks with the very best.
I have noticed that some reviewers complain when the sound quality of old recordings is not very good (eg: Okeh Ellington - which is one of my favorites). I am no expert on modern digital sound magic, but I do know that the sound quality varies on this collection. Some cuts have fairly poor sound quality.
Also, I have found two errors on the set. One is on track 19, disc 1, where a fragment of the end of the song is left floating between tracks - an editing error. The other is the reverse listing (booklet and CD jacket) of the songs "Dance of the Infidels" and "52nd Street Theme" - tracks 15 and 16 on disc 4, which actually play in the order of 16 then 15.
However, despite the poor quality of a few of the cuts, and the minor errors, the music is so awesome, that it makes little difference to this listener. It is clearly a 5-star set!
