Rock culture has always been associated with music. It is the music that defines subsequent rock culture and rock clothing. When the World War II ended, people across Europe and American continent felt a change in their lifestyle. With millions of lives lost in the war people went far ahead to shun any thought of violence, music was encouraged so that people can communicate the message of love and peace.
Great musical events were organized on a large scale, thousands of people participated in these events to listen to their favorite numbers. There was jazz, Rock music and many different types of music were played everywhere. These musicians are often seen sporting punk t shirts with weird looking punk accessories. With the introduction of heavy metal in the late 60's and early 70's new trend setters came into existence. These trendsetters laid great influence on people's mind set, and they exclusively sported rock clothing and encouraged other people in doing so.
