Urban art is an art form which epitomizes cities. Whether it be visual or performance art, Graffiti and Street art are areas commonly known and often given prejudicial treatment. It is commonly characterised by being in public domain and therefore considered to be vandalism in many minds.
Street art can be an area of landscaping or a mural on a building. The work is then photographed and brought into galleries as a record of work that may not exist for long, especially if permission has not been sought. But then that is often the point.
Graffiti is not only confined to the outside, many artists now create 2D art using graffiti as background or statement with some kind of link to life that happens in a city. It is a new era and art defines different eras – this is our now.
