From 1960-61, Hank Mobley made four albums with fellow Miles Davis bandmates Wynton Kelly and Paul Chambers. The three albums: Soul Station, Roll Call and Workout were hailed as the high points of Mobley's career and remain so to this day. Mysteriously the fourth session, which saw the trio joined by Philly Joe Jones, sat forgotten in the tape vaults until it was finally issued in 1986 as Another Workout.
