Bartz is a German family name, originating from "Bartholomäus":

Gary Bartz (born September 26, 1940, Baltimore, Maryland) is an American alto and soprano saxophonist and clarinetist.

Bartz' break into the music industry came when filling in with Art Blakey's band at Bartz' father's club in Baltimore. Bartz graduated from the Baltimore City College high school and The Juilliard School. He has worked with Miles Davis, Charles Mingus, Max Roach, and Jackie McLean. His group the "Ntu Troop" combined soul, funk, the music of Africa, hard bop, and avant-garde jazz. His performances with Miles Davis represented one of the few times from 1969 to 1974 at which a saxophonist played a saxophone other than soprano saxophone.

In the liner notes to his 1994 album The Red and Orange Poems, Jazz critic Stanley Crouch calls Bartz "one of the very best who has ever picked up the instrument".

In 2005 he won a Grammy Award for playing on McCoy Tyner's album Illuminations.

He currently teaches at the Oberlin Conservatory of Music when not touring.

McCoy Tyner (born December 11, 1938) is a jazz pianist from Philadelphia, Pennsylvania, known for his work with the John Coltrane Quartet and a long solo career.

Tyner was born Alfred McCoy Tyner in Philadelphia as the oldest of three children. He was encouraged to study piano by his mother. He began studying the piano at age 13 and within two years music had become the focal point in his life. His early influences included Bud Powell, a Philadelphia neighbor. When he was 17, he converted to Islam through the Ahmadiyya Muslim Community and changed his name to Sulieman Saud.

Tyner's first main exposure came with Benny Golson, being the first pianist in Golson's and Art Farmer's legendary Jazztet (1960). After departing the Jazztet, Tyner joined Coltrane's group in 1960 during its extended run at the Jazz Gallery replacing Steve Kuhn. (Coltrane had known Tyner for a while in Philadelphia, and featured one of the pianist's compositions, "The Believer", as early as 1958.) He appeared on the saxophonist's popular recording of "My Favorite Things" for Atlantic Records. The Coltrane Quartet, which consisted of Coltrane on tenor sax, Tyner, Jimmy Garrison on bass, and Elvin Jones on drums, toured almost non-stop between 1961 and 1965 and recorded a number of classic albums, including Live at the Village Vanguard, Ballads, Live at Birdland, Crescent, A Love Supreme, and The John Coltrane Quartet Plays ..., on the Impulse! label.
