Avant Garde from French, "advance guard" or "vanguard" are people or works that are experimental, radical, or unorthodox with respect to art, culture, or society. It may be characterized by nontraditional, aesthetic innovation and initial unacceptability, and it may offer a critique of the relationship between producer and consumer.
"Avant-Garde" pushes the boundaries of what is accepted as the norm or the status quo, primarily in the cultural realm. The avant-garde is considered by some to be a hallmark of modernism.
