Jazz critic Nat Hentoff interviewed Henderson for the album's original liner notes essay, and Henderson described the creative impulses behind several of the songs to Hentoff. The title track, "Inner Urge," which has since become a jazz standard, was a reflection of a time in his life when Henderson was "coping with the anger and frustration that can come of trying to find your way in the maze of New York, and of trying to adjust the pace you have to set in hacking your way in that city in order to just exist." Henderson also told Hentoff that "Isotope" is a tribute to Thelonious Monk and Monk's use of musical humor. Hentoff writes elsewhere in the liner notes that "El Barrio" represents Henderson's attachment to the "Spanish musical ethos", and that the piece was inspired by Henderson reflecting on his childhood in Lima, Ohio. Henderson is quoted as saying that he gave the other musicians "two simple chords, B minor and C major 7 (B phrygian)", and asked them "to play something with a Spanish feeling" while he improvised a melody for the piece.[8]
Reception
In a review on All About Jazz, Norman Weinstein calls Inner Urge Henderson's, "most emotionally urgent album" and the "ultimate showcase of his distinguished career . . . . The album seems like an apotheosis of hard bop, a ruthlessly probing amplification of a typical, hard-blowing, Blue Note bop session, pushing bop formulas as far as they could be pushed. As such, I consider it not only one of the best dozen Blue Note sessions ever released, I hear it as one of the major statements of jazz in the '60s, actually recreating the political, economic, and social realities of the turbulent times more precisely than most recorded music of the '60s in any style. An absolutely essential listen and a major masterpiece."[9]

On November 30, 1964, nine days before John Coltrane would record A Love Supreme in the same room, late tenor saxophonist Joe Henderson brought two-thirds of Coltrane's rhythm section (and bassist Bob Cranshaw) into Rudy Van Gelder's New Jersey studio and recorded an under-recognized masterpiece.
