Greasers are a working-class youth subculture that was popularized in the late 1940s and 1950s by predominately working class and lower class teenagers and young adults in the United States. The subculture remained prominent into the mid-1960s and was particularly embraced by certain ethnic groups in urban areas, though rural and suburban youth also participated in the subculture. Rock and roll music, rockabilly and doo-wop were major parts of the culture. Entertainers such as Marlon Brando and James Dean became prototypical figures that influenced the styles in this culture; others were Elvis Presley, Johnny Cash, Carl Perkins, Jerry Lee Lewis, Conway Twitty, Chuck Berry, Big Joe Williams, Big Joe Turner, Little Richard, Bo Diddley, Eddie Cochran, Gene Vincent, Johnny Burnette, Vince Taylor and Ritchie Valens.
