This is hardly a perfect recording by the world's most perfect saxophonist. He doesn't come in until minute 9 of the first tune (I was all but convinced I"d been sent the wrong CD), and a couple of the selections are clearly innocuous, paper-thin period pieces that have no business making it to a new milennium. On the other hand, there are 80 minutes of music on this compilation of two "commercial" Stitt sessions from 1972, and Sonny is soaring and splendid on each of his many opportunities. One of the rhythm sections is led by Hank Jones (with brother Thad on board) and the other by Hampton Hawes. The engineering is the "classic" Van Gelder sound throughout.The second session, issued originally under the title "So Doggone Good," features only Stitt and a three-member rhythm section. On "Speculation" Sonny reminds us of why he was so frequently compared to Bird, but what really spun my head around on this track was the percussion work of Lenny McBrowne. The tempo is way, way up and McBrowne somehow compells his left foot to play the trap cymbal on every beat!An added bonus is the thorough and truly informative set of liner notes supplied by Michael Rozek. He interviews Hank Jones as well as Eric Alexander, whose thoughts about Sonny as the most complete player and the master teacher reinforce everything I've said about him in other Amazon reviews. Rozek even supplies several websites for those who might wish additional information about this extraordinary musician.Alarm!! I've just heard "Back Door" coming through my iPhone, and the piano sound is excruciating. It's not a Rhodes or Wurlitzer, and it's not a newer digital piano by Kurzweil, etc. It sounds like the "piano sound" achievable on a Farfisa or Allen (RMI) organ by eliminating the sustain. it's obvious the piano player is struggling, since the keys are devoid of piano action, stoppers, and natural feel. Hard to believe tracks like this made it through the final edit.
