Andy Goldsworthy: A British sculptor and photographer, known for works like his egg-shaped cairns and “Collaborations with Nature,” which demonstrate the art of rock balancing.

A 2001 documentary, Rivers and Tides, is based around Goldsworthy’s life and work.Ash: Originally known as Saho and Ash2, Ash was a member of the Parisian graffiti collective Badbc (BBC), along with artists JayOne and Skki. He was inspired by New York City subway graffiti, and kicked off the popularity of street art in Europe before Bansky came on the scene. Ash displayed some of his works in the 1989 exhibition “Les peintres de la ville” at the Galerie du Jour in Paris, and his more recent works have been commissioned by city districts and museums.Beautiful Angle: A wheatpasting duo from Tacoma, Washington.

The duo has won a Chamber of Commerce award of merit and has been featured in the City Arts Magazine and The News Tribune. Several gallery shows have been held around the city.Christo and Jeanne-Claude: A married couple that created large works of environmental art across the world. Their most famous works included Running Fence, a 24.5-mile long installation in California made by hanging white nylon fabric from steel cables, and The Gates, a 23-mile installation in Central Park where deep saffron-colored nylon was hung from 16-foot-tall “gates.”Jean-Michel Basquiat: Basquiat was a graffiti artist from New York City who moved into producing neo-expressionist paintings in the 1980s. His works achieved international acclaim. His early graffiti, done in high school, included poetry ascribed to SAMO and appeared on buildings in lower Manhattan, while his later works were presented in SoHo art galleries, including the Mary Boone gallery. His works often included references to African mythology and history.Michael Kirby: A street artist from Baltimore, Maryland who studied in Italy and became proficient in fresco painting. He applies these techniques to street painting to create three-dimensional murals, such as Life of Pocahontas, which was created for the 400^th Anniversary Celebration of Werowocomoco (Pocahontas’s village in Gloucester, Virginia). He’s also been contracted by McDonald’s, Honda, Johns Hopkins University, the Black Eyed Peas, and others to create works.Richard Serra: A minimalist sculptor known for large-scale installations using sheet metal. For example, the installation Tilted Arc (1981) is a curved, 3.5 meter-tall arc of rusting steel placed in the Federal Plaza of New York City. Ultimately, workers in nearby buildings complained that the work blocked access, and the sculpture was eventually dismantled by the federal government and used as scrap.
