''Thelonious Himself'' is a 1957 album by Thelonious Monk and his first to consist of exclusively solo material including "'Round Midnight", Monk's most famous composition. The original CD reissue includes a revelatory 22 minutes of "'Round Midnight" outtakes, ideas, and development. The Keepnews Collection edition omits this sequence. In the liner notes Keepnews states that including it "would have required eliminating virtually every existing alternate take of other selections — five other examples of this pianist's improvisational genius."

The album was originally released in June 1959, featuring saxophonist John Coltrane. - Wikipedia
