Jack Montrose (1928 - 2006) was a jazz tenor saxophonist and arranger. After attending university in Los Angeles he worked with Jerry Gray and then Art Pepper. Montrose also did arrangements for Clifford Brown. He became known for cool jazz and/or West coast jazz. Beginning in the mid-1950s Montrose's heroin addiction became a liability and by the time he had overcome it his style of jazz was no longer popular.
