Frank Vincent Zappa (December 21, 1940 – December 4, 1993) was an American musician, composer, activist and filmmaker. His work was characterized by nonconformity, free-form improvisation, sound experiments, musical virtuosity, and satire of American culture. In a career spanning more than 30 years, Zappa composed rock, pop, jazz, jazz fusion, orchestraland musique concrète works, and produced almost all of the 60-plus albums that he released with his band the Mothers of Invention and as a solo artist. Zappa also directed feature-length films and music videos, and designed album covers. He is considered one of the most innovative and stylistically diverse rock musicians of his era.
As a self-taught composer and performer, Zappa's diverse musical influences led him to create music that was sometimes difficult to categorize. While in his teens, he acquired a taste for 20th-century classical composers such as Edgard Varèse, Igor Stravinsky, and Anton Webern, along with 1950s rhythm and blues and doo-wop music. He began writing classical music in high school, while at the same time playing drums in rhythm and blues bands; later switching to electric guitar. His 1966 debut album with the Mothers of Invention, Freak Out!, combined songs in conventional rock and roll format with collective improvisations and studio-generated sound collages. He continued this eclectic and experimental approach, irrespective of whether the fundamental format was rock, jazz or classical.
