Duane Eddy was an American rock and roll guitarist. In the late 1950s and early 1960s, he had a string of hit records produced by Lee Hazlewood which were noted for their characteristically "twangy" guitar sound, including "Rebel-'Rouser", "Peter Gunn", and "Because They're Young". He had sold 12 million records by 1963. His guitar style influenced the Shadows, the Beatles and Bruce Springsteen.

The Savage Seven is a 1968 outlaw biker exploitation film directed by Richard Rush, who had directed the previous year's Hells Angels on Wheels. Rush agreed to direct The Savage Seven in exchange for the opportunity to make the psychedelic film Psych-Out.
