The correct answer is Warne Marsh
Along with Lee Konitz, Warne Marsh was the most successful “pupil” of Lennie Tristano and, unlike Konitz, Marsh spent most of his career exploring chordal improvisation the Tristano way. The cool-toned tenor played with Hoagy Carmichael’s Teenagers during 1944-1945 and then after the Army, he was with Buddy Rich (1948) before working with Lennie Tristano (1949-1952). His recordings with Tristano and Konitz still sound remarkable today with unisons that make the two horns sound like one. Marsh had occasional reunions with Konitz and Tristano through the years, spent periods outside of music, and stayed true to his musical goals. He moved to Los Angeles in 1966 and worked with Supersax during 1972-1977, also filling in time teaching. Marsh, who collapsed and died on stage at the legendary Donte’s club in 1987 while playing “Out of Nowhere,” is now considered legendary. He recorded as a leader for Xanadu, Imperial, Kapp, Mode (reissued on V.S.O.P.), Atlantic, Wave, Storyville, Revelation, Interplay, Criss Cross, and Hot Club.
