Bussotti is also a well-known film director, actor, and singer. His uncle Tono Zancanaro and his older brother Renzo Bussotti strongly influenced his style in painting. He has written most of the librettos of his operas. As a writer, his style is considered one of the most refined among the Italian poets and novelists of 20th century. French culture has fascinated him since he was a boy. His great friend Cathy Berberian (Luciano Berio's wife) was one of his most famous interpreters. He was, or is, well acquainted with writers and film directors Aldo Palazzeschi, Pier Paolo Pasolini, Derek Jarman, Elsa Morante, Alberto Moravia, Aldo Braibanti, Mario Zanzotto, Fabio Casadei Turroni, Dacia Maraini, Umberto Eco. Derek Jarman was the director of his opera L'Ispirazione, first staged in Florence in 1988. Rara Film is his most celebrated underground film. The film, according to the author's instructions, should be performed, together with the score, which includes from seven to eleven players. The music of Rara Film is not a strict counterpoint of the film, flowing without any relation to the images.
He has served as the artistic director of La Fenice, Venice. As a personality he is notoriously flamboyant and occasionally shocking. He staged a high-profile resignation from the Venice Biennale in 1991 by bringing in a famous prostitute to give the keynote speech. Outspoken and openly gay, Bussotti expressed his sexuality in his music as early as 1958.
