概念藝術
Conceptual Art sought to expand aesthetic boundaries in its critique of notions of the art object and the commodity system within which it is circulated as currency. Conceptual artists experimented with unconventional materials and processes of art production. Grounded by strategies rooted in the real world, projects in conceptual art demanded viewer participation and were exhibited outside of the traditional and exclusive space of the art gallery, thus making the work accessible to the public. Similarly, collaborative methods of execution and expertise drawn from outside the art world are often employed in activist art so as to attain its goals for community and public participation. Parallel to the emphasis on ideas that conceptual art endorsed, activist art is process-oriented, seeking to expose embedded power relationships through its process of creation.
