Premise: Frank Zappa . In a career spanning more than 30 years , Zappa composed rock , pop , jazz , jazz fusion , orchestral and 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 . 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 .
Hypothesis: Frank Zappa was not a composer.
