Does anyone know about books and materials about the art and culture of black graffiti in America or the history of black graffiti art and culture in America? I really need more authoritative information. From11960 s to 1980 s, new york urban area was a city full of enthusiasm and emphasized fast pace. The narrow living environment exposes the life on the street, and the gap between the rich and the poor in society is large enough to form a so-called anti-cultural group for people living on the edge of subculture society under such social pressure. What's more, there are a group of Hispanic or black youths who are unemployed and drop out of school in slums as social problems. In the ideological trend of anti-racial discrimination, anti-war, anti-sexual repression and anti-right repression, they touched on the racial problems, poverty and employment constraints brought about by the living environment, and formed a regional anti-cultural social behavior. These behaviors include street basketball, street graffiti, street dance, hip &；; HOP, RAP rap songs and other activities. Among them, graffiti culture originated from the edge of new york society, and a group of children who dared to challenge American government authorities rebuilt the fragments of secular culture. Among them, graffiti culture began in the late 1960s and flourished in the 1980s. From the late 1970s to the 1980s, a group of graffiti lovers made a living by it, developed their own unique graffiti art, expressed their views and had distinct personalities. In the later stage, it is no longer a simple anti-cultural social behavior, but something with art is added to make it more acceptable and legal. Walk slowly from underground to the ground.

Graffiti itself is a rebellion against authority, and graffiti is also an artistic expression. From the artistic point of view, through such behavior, performance art can quickly attract the attention of social politics, media, mainstream art, traditional art and cultural circles, so graffiti characters gradually decrease and become large and exquisite cartoon painting images. Academic artists followed suit, so professional graffiti artists began to appear, and groups like leagues and societies also appeared. After that, graffiti art began to enter the art museum for people to appreciate, collect, buy, sell and invest. Since then, the nature of graffiti culture has changed greatly. As a result, there has been an upsurge of graffiti culture all over the world. Graffiti art is very similar to rock music, but also rap music. At first, people used this kind of creation to resist the system, express their dissatisfaction, vent their emotions and blame the society. Later, the original essence of these graffiti arts was incorporated into the whole capital system, and the original counterculture art became a branch of real art and became an art with the same nature as traditional painting. The originality of graffiti has gradually disappeared in graffiti creation in other countries. From 1970s to 1980s, galleries in new york began to hold various graffiti cultural exhibitions and invited street graffiti artists to the galleries, so graffiti became a high-pressure artistic creation form. Important exhibitions include: 1. The first graffiti art exhibition was held at 1972 in the Blade Gallery of Soho in Manhattan, new york. 2. From 65438 to 0975, the joint graffiti artists exhibited in new york Artists Space. 3. The Times Square Exhibition was launched1980-Graffiti really began to be displayed in large quantities, which attracted great attention from the art world. 4. 1983 is the peak of graffiti art, and the first exhibition of art galleries was held in Boyman-van Beuningen Museum in Rotterdam.
