Stan's seemed to be Mickey Mouse turned upside down or something hurting it,' Yorke recalls. 'Mine was usually the same lyrics repeated page after page after page, with slight alterations. Both had carried notebooks with them since art school. 'They seemed to fade into nothing,' Thom notes. Over time, the fax imagery disappeared due to the deterioration of the thermal fax paper. 'Loads of expletives and scribblings,' Yorke concurs. 'With headed notepaper from fancy hotels, which is always nice experiencing the life of the international jet set vicariously,' recalls Donwood wryly.

Yorke and Donwood would send scrawled faxes instead. I don't think either of us particularly like the telephone.' In 1999, the internet and emails were still in their infancy and sharing images online was a long-winded process.

'We were thoroughly obsessed with fax machines at the time. 'It was a sort of a form of communicating to be honest,' Yorke recalls. Neither imagined that the pages torn from their sketchbooks would one day be seen in any formal way.

This exhibition brings together 60 works on paper created by the pair over the course of 19. Their drawings - which often fed into record covers, Radiohead's expanded website and other visual material - are more like diptychs than duets. Instead, they designed an alternative way of thinking about creativity: two people producing in tandem, working concurrently, continually bouncing images and ideas off each other.

How do you rethink collaboration? It's true to say that Thom Yorke and Stanley Donwood have never worked together in an obvious fashion.
