Chuck Berry died on Saturday afternoon at his home outside St. Louis. aged 90. Emergency responders found the rock n’ roll legend unconscious at his home and was later pronounced dead. Berry performed the blues at his high school and later emerged as a star guitarist at the birth of rock. His signature duck walk was apparently invented to make his mother laugh as a child. Berry performed for presidents and was a major influence for Lennon, McCartney and Bruce Springsteen.
