In a radical action like Nam June Paik destroying a violin, and rolling up in bandages the bodies of the players in in a concert by Yoko Ono, the international avant-garde group Fluxus changed not only art, but the concept of it.
""Taka iimura is a senior figure among contemporary Japanese artists and has been working with film, sound and video since the 1960s. He was one of several Japanese who, coming from a 20th Century tradition of avant-garde intervention, contributed to the Fluxus group in the 60s... As the cycle of experimentation moves through another generation, glimpses of precursors through archive recordings of this kind help ground artists’ surviving words and artworks."
