Watch on Soap2day. Documentation of the 2-hour performance by Marina Abramović and Ulay, performed in 1978 at Harlekin Art in Wiesbaden. In this piece, the two artists and a live snake triangulate the performance space. By blowing across the mouths of empty bottles, Abramović and Ulay produce sounds meant to rouse the snake, attempting to charm it and alter the physical geometry of the arrangement.
