Only Monk is the third album by Steve Lacy to be released on the Italian Soul Note label (following two releases on the related Black Saint label). It features solo performances of nine tunes written by Thelonious Monk by Lacy. It is the second solo album composed totally of Monk's compositions recorded by Lacy following Eronel (1979) and follows a tradition established on Lacy's second album Reflections (1958) and Epistrophy (1969).
The Allmusic review by Scott Yanow awarded the album 4 stars stating "Steve Lacy has long been one of the foremost interpreters of pianist Thelonious Monk's music. This set is a solo soprano saxophone recital in which Lacy digs into nine of Monk's compositions. Most of the interpretations are quite concise, with all but the seven-minute "Work" clocking in at under six minutes. As usual, Lacy shows great respect for the melodies, and his improvisations are built off of the themes rather than just the chord changes. The sparse setting allows the soprano master to utilize space effectively and to take his time. The overall results, which are certainly for selective tastes, are often fascinating.".
