In the late 1970s, a new art form was born on urban the streets of Manhattan. Young kids—often frustrated with convention—armed with spray cans “tagged” the cold steel of dormant subway cars and buildings in shadowy alleys, only to emerge as the sun rose as roving artwork embraced on the streets. Some of these artists went on to lucrative design careers; others went to jail. Now, twelve top graffiti artists in Hawai‘i will compete in the “Estria Invitational Graffiti Battle” at the Honolulu Academy of Arts at Linekona Art Center this Saturday, Sept. 3, from noon to 7:00 p.m.
