Pioneer of performance art, Marina Abramović is one of the most acclaimed, remarkable and influential contemporary artists in the world today. Born in Belgrade in 1946, she pushes the boundaries of both body and mind in works such as the now-legendary "Rhythm 0" where she relinquished all control to her audience and for eight hours permitted them to use a series of objects, including a gun, on her person. Abramović's most recent show, "As One," is at the Benaki Museum in Athens, where she has been mentoring young Greek performance artists as well as introducing her audience to The Abramović Method, as practised by Lady Gaga.
