Generally, when you think of the word "avant-garde" you think of art, music, or literature that goes against convention. In simple terms, avant-garde work is a little weird. The meaning of the term originated in military speak, where it referred to the "advanced guard," a group of soldiers that moved ahead in front of the group. This may relate to how we use it to describe the arts in that "avant-garde" artists always seem to be pushing the limits of art. Considered the quintessential example of avant-garde art is the Dada movement-a movement that questioned what art is.
