Curators and critics struggled to define the essence of this artistic production, coining terms such as Post-painterly, Lyrical Abstraction, Color Field, Hard-Edge, Minimalist and Systems. Artists such as Larry Bell, Thomas Downing, Helen Frankenthaler, Stephen Greene, Kenneth Noland, Frank Stella and Jack Youngerman produced work that has been included in one or more of these categories. Some artists, Ellsworth Kelly and Agnes Martin among them, were outspoken in dissociating their work from such classifications. Many of these painters belonged to overlapping social and professional circles, providing each other with support for their innovations and efforts. And dealers such as Betty Parsons and Leo Castelli in New York and Irving Blum at Ferus in Los Angeles exhibited them and promoted their work. Surface Truths, drawn from the Museum’s holdings, presents seminal and seldom-seen work by these artists who blazed an important trail through the contemporary art world.
