Avant-garde art refers to innovative and experimental works that challenge traditional artistic norms and conventions. It often seeks to push boundaries and provoke thought, encouraging viewers to reconsider their perceptions of art and society. This movement spans various mediums, including painting, sculpture, music, and literature. Emerging in the late 19th and early 20th centuries, avant-garde artists like Marcel Duchamp and Pablo Picasso sought to break away from established styles. Their work often incorporates unconventional materials and techniques, reflecting a desire for artistic freedom and exploration. This approach has influenced many contemporary art movements and continues to inspire artists today.
