Yoko Ono's extraordinary performance piece features members of an orchestra who are wrapped in gauze as they perform. This was performed on 23 June 2013 by Southbank Sinfonia in Purcell Rooms at Southbank Centre as part of the Future Now weekend, a weekend of talks and events programmed by this year's Meltdown Festival curator, Yoko Ono.
