Composer, guitarist, singer, and bandleader Frank Zappa was a singular musical figure during a performing and recording career that lasted from the 1960s to the ’90s. His disparate influences included doo wop music and avant-garde classical music; although he led groups that could be called rock & roll bands for much of his career, he used them to create a hybrid style that bordered on jazz and complicated, modern serious music, sometimes inducing orchestras to play along. As if his music were not challenging enough, he overlay it with highly satirical and sometimes abstractly humorous lyrics and song titles that marked him as coming out of a provocative literary tradition that included Beat poets like Allen Ginsberg and edgy comedians like Lenny Bruce.
