Frank Vincent Zappa was an American singer-songwriter, multi-instrumentalist, composer, and bandleader. His work is 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, orchestral and musique concrte 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 modernism, African-American 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.
