Jersey Shore sound

The Jersey Shore sound is a genre of rock and roll popularized at the Jersey Shore on the Atlantic Ocean coast of New Jersey, United States.
The Jersey Shore sound evolved from the mixing of pre-Beatles rock and roll, rhythm and blues, doo-wop, and the urban culture of the Mid-Atlantic states. The form has a strong Italian-American influence inasmuch as many of the form's key precursors and artists, from Frankie Valli through Bruce Springsteen, are of Italian ancestry and urban background. 
Jersey Shore music shares two thematic elements with the genres of heartland rock and roots rock: A focus on the daily lives of people (in this case, those living in the stereotypically industrial society of the northeast United States, Northern and Central Jersey) and a sense of being the underdog (a theme in the genre from The Four Seasons' "Rag Doll", "Walk Like a Man", and "Big Man in Town" and through Springsteen's "Dancing in the Dark").. Traditionally it also is known by its horn section.
