Famed minimalist Richard Serra, perhaps best known for his site-specific sculptures, has created works that span the mediums, including drawing and video, and that cross the continents from America to Asia. The single most important characteristic of his art is its pure physicality; the presence of his work, either because of materials or the site, is always insistent and, at times, unsettling. Frequently using industrial materials, Serra's sculptures evoke a sense of rawness while their towering heights and simple lines forcefully transgress into the viewer's space. In his series Tilted Arcs (1996-1999) monumental sheets of steel curve through public spaces, creating private enclaves even as these interventions shatter prior relationships with said spaces. His works have been at exhibited the Venice Biennale and the Whitney Biennial, as well as at numerous institutions including the Guggenheim Museum, the Museum of Modern Art, and the Metropolitan Museum.
