The first song, "Abide With Me"—a hymn by W. H. Monk—is played only by the septet's horn section. The song "Ruby, My Dear" is performed only by Monk, Coleman Hawkins, Wilbur Ware, and Art Blakey. John Coltrane had joined Monk after playing with the Miles Davis Quintet, and Monk can be heard enthusiastically calling on him ("Coltrane! Coltrane!") to take the first horn solo on the album in "Well, You Needn't." All of the tracks except "Abide With Me" are original compositions by Monk; all of the originals but "Crepuscule with Nellie" had previously appeared on record. This is the only record where Hawkins and Blakey recorded together.
Mono vis-à-vis stereo
This was the first Riverside Thelonious Monk album recorded and released in both mono (RLP 12-242) and stereo (RLP 1102). The stereo version was released nine months after the mono release, in August 1958.[8] It has been noted that the mixes of these releases are extremely different. The stereo mix, while featuring the same performances as does the mono version, used an entirely different set of microphones, suspended from the ceiling, while the mono release used microphones in closer proximity to the instruments. As a result, the stereo mix has a more distant sound and Wilbur Ware's bass is much less audible.[9]
Our new stereo series had begun with a sound effects disc, so Riverside 1102 [Monk's Music] was our first stereo jazz album. But we had to deal with the fact that the studio had not yet taken the drastic step of converting to the new process: the installed equipment at Reeves Sound Studios (on 2nd Avenue between 44th and 45th Streets in Manhattan) was still monaural. Thus, we had to improvise a dual system. Studio engineer Jack Higgins presided at his usual control panel; our staff engineer Ray Fowler was in the soundproof isolation booths in the studio with a newfangled portable stereo tape recorder. Thus, on this and several subsequent occasions, ‘binaural’ was an entirely separate operation. Among other things, every musician found himself surrounded by a doubled quantity of microphones.”[10]
In the notes to the 1986 Riverside Monk box, Keepnews wrote: "This was one of our very first stereo recordings (although the separate machine failed us on Crepuscule); confusingly, the monaural version has sometimes been used in reissues, but I have managed to include here in stereo form everything that is available in that form."[11]
The original stereo LP release did not list "Crepuscule with Nellie" on its label or cover track listing, although it was referenced in the liner notes, and did not include it on the album. A mid-1960s stereo re-release with serial number RLP 12-9242 also skipped "Crepuscule with Nellie", even though it was listed on the label and cover (as "Crepescule with Nellie" [sic]). The 1967 "stereo" pressing (RS 3004) distributed by ABC Records was an "electronically reprocessed" version of the mono mix. A 1977 Japanese vinyl version appears to be the first true stereo release that also includes the mono recording of "Crepuscule with Nellie".[12]
