Grassroots art is a term describing art made by people with no formal artistic training . . . (usually of retirement age) using ordinary materials in an extraordinary way . . . and frequently creating a whole artistic environment around themselves, effectively making themselves part of the artwork.
Such work tends to be difficult to classify because it falls outside the sphere of fine art as well as that of traditional folk art in which skills and patterns may be passed from one generation to another.
Whether it’s called art brut or outsider art, the phenomenon is world-wide, with sites identified from France to India, Switzerland to Thailand, and all over the United States.
