In the post World War II boom, culture and music played a huge part in reshaping American Identify.
Elvis Presley came out as one of the most popular rock n roll artists of the era while Marlon Brando and James Dean were popular among a specific audience who felt like they had a larger role in their life.
All these artists were able to connect with teenagers of the time who had a sense of pride in the American dream.
