here's how wikipedia describes Frank Zappa,

Frank Vincent Zappa (1940 – 1993) was an American
composer, electric guitarist, record producer and film
director. In a career spanning more than 30 years,
Zappa wrote rock, jazz, electronic, orchestral, and
musique concrète works . . .

Many of his albums are considered essential in rock
history, and he is regarded as one of the most original
guitarists and composers of his time; he remains a
major influence on musicians and composers . . .

Zappa was posthumously inducted into the Rock and
Roll Hall of Fame in 1995 and received the Grammy
Lifetime Achievement Award in 1997.
