This album was originally released as Donald Byrd & Pepper Adam's "Out of This World" album in 1961 on Warwick Records. Soon on the wave of growing Hancock's popularity it was re-released as Hancock's album by few labels and with different album names ("Jamming With Herbie". And even more - even if all album versions contain mostly same compositions (some later CD re-releases have bonus tracks), almost all of them were renamed for Hancock's album. Musicians on this album include Pepper Adams, Laymon Jackson, Jimmy Cobb, Herbie Hancock & Donald Byrd.
