2017 marks two decades since the release of Radiohead's OK Computer and the band have shared a mysterious video sparking speculation that they will be marking the occasion in some way.

The short video, shared via Twitter, shows a glitchy computer screen and features a child reciting lyrics from OK Computer track 'Climbing Up The Walls'.

The tweet follows a number of posters which appeared last week in cities such as London, Berlin, New York and Los Angeles which initially set off speculation about impending anniversary celebrations by the band. The band will headline Glastonbury Festival in June 20 years on from their first headline performance at the festival.
