Leonard Joseph "Lennie" Tristano (March 19, 1919 – November 18, 1978) was an American jazz pianist, composer, arranger, and teacher of jazz improvisation.
Tristano studied for bachelor's and master's degrees in music in Chicago before moving to New York City in 1946. He played with leading bebop musicians and formed his own small bands, which soon displayed some of his early interests – contrapuntal interaction of instruments, harmonic flexibility, and rhythmic complexity. His quintet in 1949 recorded the first free group improvisations. Tristano's innovations continued in 1951, with the first overdubbed, improvised jazz recordings, and two years later, when he recorded an atonal improvised solo piano piece that was based on the development of motifs rather than on harmonies. He developed further via polyrhythms and chromaticism into the 1960s, but was infrequently recorded.
Tristano started teaching music, especially improvisation, in the early 1940s, and by the mid-1950s was concentrating on teaching in preference to performing. He taught in a structured and disciplined manner, which was unusual in jazz education when he began. His educational role over three decades meant that he exerted an influence on jazz through his students, including saxophonists Lee Konitz and Warne Marsh.
Lennie Tristano, also known as Tristano, is a 1956 album by jazz pianist Lennie Tristano. At its release, the album was controversial for its innovative use of technology, with Tristano overdubbing piano and manipulating tape speed for effect on the first four tracks. The final five songs are concert recordings. Originally released as Tristano's Atlantic Records debut, the album was released on CD in 1994 by Rhino Records in combined form with Tristano's 1960 follow-up, The New Tristano, and as part of a collection, The Complete Atlantic Recordings of Lennie Tristano, Lee Konitz & Warne Marsh, in 1997. It was subsequently re-issued in original form and track-list order by Warner Jazz (2002), Rhino (2003) and Collectables (2004).
In 1997, The New York Times dubbed the album a masterpiece.AMG describes the album as "gorgeous...with a beautiful juxtaposition between the first half and the second half between the rhythmic and intervallic genius of Tristano as an improviser and as a supreme lyrical and swinging harmonist on the back half".
