Notes

Tracks 2, 6, and 8 recorded on December 14, 1967, 4 and 9 on December 21, 1967, and 1, 3, 5, 7, and 10 on February 14, 1968.
Mastered at Sony Music Studios, NYC.
Tracks 8 to 10 are bonus tracks, not on original LP.
Tracks 8 and 9 are previously unreleased.
"The CD presents, in sequence, the seven selections that appeared on the original LP, followed by three alternates. Take numbers identify each version of the duplicated selections. However, as initially released, only two of the seven pieces were heard in full as they had been recorded. All but 'Thelonious' and 'Boo Boo's Birthday' were either briefly trimmed or severly edited -- possibly in order to include a version of each recorded number despite the time limitations of the LP form . . . One specific intention of this reissue disc is to present the material basically as Monk played it in the studio. (Another act of restoration is not to turn off Hendricks' track when he finishes his scat chorus, thus preserving his spontaneous bursts of enthusiasm throughout 'In Walked Bud.')"
