"Hot rod music" or "hot rod rock" evolved from surf music. Dick Dale recalled how surf music was re-imagined as hot rod music by a record company-inspired move to capture a larger market. According to "The Ultimate Hot Rod Dictionary", by Jeff Breitenstein: "While cars and, to a lesser degree, hot rods have been a relatively common and enduring theme in American popular music, the term "hot rod music" is most often associated with the unique 'California sound' music of the early to mid-1960s ... and was defined by its rich vocal harmonies, amplified (generally Fender brand) electric guitars, and youth-oriented lyrics (most often celebrating hot rods and, more broadly, surfing and 'girls')."
