György Sándor Ligeti (; Hungarian: [ˈliɡɛti ˈɟørɟ ˈʃaːndor]; 28 May 1923 – 12 June 2006) was a Hungarian composer of contemporary classical music. He has been described as "one of the most important avant-garde composers in the latter half of the twentieth century" and "one of the most innovative and influential among progressive figures of his time". Born in Romania, he lived in the Hungarian People's Republic before emigrating to Austria in 1956. He became an Austrian citizen in 1968. In 1973 he became professor of composition at the Hochschule für Musik und Theater Hamburg, where he worked until retiring in 1989. His students included Hans Abrahamsen, Unsuk Chin and Michael Daugherty. He died in Vienna in 2006. Restricted in his musical style by the authorities of Communist Hungary, only when he reached the West in 1956 could Ligeti fully realise his passion for avant-garde music and develop new compositional techniques. After experimenting with electronic music in Cologne, Germany, his breakthrough came with orchestral works such as Atmosphères, for which he used a technique he later dubbed micropolyphony. After writing his "anti-anti-opera" Le Grand Macabre, Ligeti shifted away from chromaticism and towards polyrhythm for his later works. He is best known by the public through the use of his music in film soundtracks. Although he did not directly compose any film scores, excerpts of pieces composed by him were taken and adapted for film use. The sound design of Stanley Kubrick's films, particularly the music of 2001: A Space Odyssey, drew from Ligeti's work.

Atmosphères is a piece for orchestra, composed by György Ligeti in 1961. It is noted for eschewing conventional melody and metre in favor of dense sound textures. After Apparitions, it was the second piece Ligeti wrote to exploit what he called a "micropolyphonic" texture. It gained further exposure after being used in Stanley Kubrick's film 2001: A Space Odyssey.

The Concerto for Cello and Orchestra is a cello concerto by György Ligeti written in 1966. It is dedicated to cellist Siegfried Palm, who gave the concerto its premiere performance.

A flute concerto is a concerto for solo flute and instrumental ensemble, customarily the orchestra. Such works have been written from the Baroque period, when the solo concerto form was first developed, up through the present day. Some major composers have contributed to the flute concerto repertoire, with the best known works including those by Mozart and Vivaldi. Traditionally a three-movement work, the modern-day flute concerto has occasionally been structured in four or more movements. In some flute concertos, especially from the Baroque and modern eras, the flute is accompanied by a chamber ensemble rather than an orchestra.

The Concerto for Piano and Orchestra by György Ligeti is a five-movement piano concerto. Ligeti wrote: I present my artistic credo in the Piano Concerto: I demonstrate my independence from criteria of the traditional avantgarde, as well as the fashionable postmodernism. Musical illusions which I consider to be also so important are not a goal in itself for me, but a foundation for my aesthetical attitude. I prefer musical forms which have a more object-like than processual character. Music as "frozen" time, as an object in imaginary space evoked by music in our imagination, as a creation which really develops in time, but in imagination it exists simultaneously in all its moments. The spell of time, the enduring its passing by, closing it in a moment of the present is my main intention as a composer. It is dedicated to the American conductor Mario di Bonaventura who premiered the work.

Seiji Ozawa (小澤 征爾, Ozawa Seiji; September 1, 1935 – February 6, 2024) was a Japanese conductor known internationally for his work as music director of the Toronto Symphony Orchestra, the San Francisco Symphony, and especially the Boston Symphony Orchestra (BSO), where he served from 1973 for 29 years. After conducting the Vienna New Year's Concert in 2002, he was director of the Vienna State Opera until 2010. In Japan, he founded the Saito Kinen Orchestra in 1984, their festival in 1992, and the Tokyo Opera Nomori in 2005. Ozawa rose to fame after he won the 1959 Besançon competition. He was invited by Charles Munch, then the music director of the BSO, for the following year to Tanglewood, the orchestra's summer home, where he studied with Munch and Pierre Monteux. Winning the festival's Koussevitzky Prize earned him a scholarship with Herbert von Karajan and the Berlin Philharmonic and brought him to the attention of Leonard Bernstein, who made him his assistant with the New York Philharmonic in 1961. He became artistic director of the festival and education program in Tanglewood in 1970, together with Gunther Schuller. In 1994, the new main hall there was named after him. Ozawa conducted world premieres such as György Ligeti's San Francisco Polyphony in 1975 and Olivier Messiaen's opera Saint François d'Assise in Paris in 1983. He received numerous international awards. Ozawa was the first Japanese conductor recognized internationally and the only one of superstar status.
