If you have the original 10" LP issue of this album with the '50s David Stone Martin cover art, hang on to it (it's worth anywhere from $240 to $400!), but also acquire this greatly expanded CD version in the Verve Master Edition series. In addition to the original eight selections, recorded in 1953 with Al Haig or Hank Jones (piano), Percy Heath or Teddy Kotick (bass), and Max Roach (drums), you get an awesome variety of other Parker quartet, quintet, and septet sessions, plus extensive outtakes and false starts (grouped at the end of the disc) from the 10" LP sessions. Bird was still in marvelously inventive form in 1953, hardly ever repeating the same idea twice, clearly inspired by the propulsive Roach groove.
