J. R. Monterose (January 19, 1927 – September 16, 1993), born Frank Anthony Peter Vincent Monterose, Jr. in Detroit, Michigan, was an American jazz tenor (and occasional soprano) saxophonist.J.R. or JR (derived from Jr.) Monterose grew up in Utica, New York, where his family moved a few months after his birth. He began formal clarinet studies at thirteen, but was largely self-taught as a tenor saxophonist, which he took up at fifteen after hearing Glenn Miller band soloist Tex Beneke. His earliest stylistic influences were Coleman Hawkins and Chu Berry, but, as he told critic Leonard Feather, he also found harmonic inspiration in pianists, citing particularly the example of Bud Powell and the instruction of Utica-based guitarist and pianist Sam Mancuso in helping him learn how to use chord changes. 　　J.R. Monterose (not to be confused with fellow tenor Jack Montrose) is most famous for a gig that he personally did not enjoy, playing with Charles Mingus in 1956 and recording on Mingus breakthrough album Pithecanthropus Erectus. He grew up in Utica, NY, played in territory bands in the Midwest, and then moved to New York City in the early 50s. Monterose played with Buddy Rich (1952) and Claude Thornhill and recorded with (among others) Teddy Charles, Jon Eardley, and Eddie Bert. After leaving Mingus (whom he did not get along with), Monterose played with Kenny Dorhams Jazz Prophets and recorded a strong set for Blue Note as a leader. Although he performed into the 1980s (doubling on soprano in later years), Monterose never really became famous. In addition to his Blue Note date, he led sets for Jaro (a 1959 session later reissued by Xanadu), Studio 4 (which was reissued by V.S.O.P.), a very obscure 1969 outing for the Dutch label Heavy Soul Music (1969), and, during 1979-1981, albums for Progressive, Cadence, and two for Uptown.
