Peformance Art is where the artwork takes the form of actions performed by the artist/s or approved performers briefed by the artist.
In Europe, the German artist Joseph Beuys was a hugely influential pioneer of Performance art, making a wide impact with his 'actions' from 1963 onwards. At around the same time in the UK, it was the artist duo Gilbert & George taking the scene by storm.
Sorry, no pics were here that could depict the Preformance Art.
