By 1970 Landfield was recognized as one of the first painters to have led the "movement away from the geometric, hard-edge, and minimal, toward more lyrical, sensuous, romantic abstractions in colors which were softer and more vibrant." His paintings were part of the Whitney Museum of American Art's Annual exhibitions in 1967 and 1969, and he was included in the first Whitney Biennial in 1973. During the late 1960s through the early '70s his work was included in group exhibitions at the Park Place Gallery, the Bianchini Gallery, the Bykert Gallery, the Sheldon Memorial Art Gallery, the Whitney Museum of American Art, the Museum of Modern Art, the Baltimore Museum of Art, the Studio Museum in Harlem, and the Iris & B. Gerald Cantor Center for Visual Arts (formerly Stanford University Museum of Art) amongst other places. In 1967-1968 two drawings were reproduced in "S.M.S. III" by the Letter Edged in Black Press, and he was included in "New York 10" 1969, a portfolio of prints published by Tanglewood Press.
