“We wanted to have a commission that would suggest that the Hayward was reawakening again after being in hibernation for over two years and it would be a small drumroll announcing that we will be opening our doors soon,” says the Hayward Gallery director Ralph Rugoff Pete Woodhead
Although Sixty Minute Spectrum is due to end on 25 March 2018, it may remain in place for "several years", Rugoff says Pete Woodhead
