Hip hop is composed of four elements; graffiti, DJ(disc jockey)/turntablism, b-boy and MC. Graffiti became popular in the 1970's to 1980's, and a lot of its history can be seen in New York City, on large brick walls and subway stations such as the 149th street Grand Concourse station in the Bronx. This station has a bench called the Writer's Bench. The bench, located at the back of the uptown platform, is where writers from all over the city came to meet, make plans, sign black books and settle disputes. The main activity was benching or watching art on the passing trains. The writers would admire and criticize the latest paintings.
