Frank Morgan - Mood Indigo (1989)

This ballad-oriented set features veteran altoist Frank Morgan on four duets with pianist George Cables, interacting with either Cables or Ronnie Mathews on piano, bassist Buster Williams and drummer Al Foster on the other selections, and welcoming trumpeter Wynton Marsalis to "Bessie's Blues" and "Up Jumped Spring." Every Morgan recording is well worth picking up (the altoist has been very consistent in the studio), but this one purposely has less mood variation than most and is often a bit melancholy.
