Founded in New Mexico in 1938, at a time when social realism reigned in American art, the Transcendental Painting Group (TPG) sought to promote abstract art that pursued spiritual illumination. Despite the quality of their works, these Southwest artists have been neglected in most surveys of American art. This title aims to address this slight, claiming the group’s artists as crucial contributors to an alternative through-line in 20th-century abstraction, one with renewed relevance today.
