In 2017, Radiohead fans got a very exciting release from the band. To celebrate the 20th anniversary of their landmark album OK Computer, the group released a thorough box set of material from their sessions, onto a cassette tape (that featured a ZX Spectrum program hidden in it as an easter egg). The tape offered fans some rare unreleased and early material as well as bits of sound collages that would end up hidden in the finished album.What fans were not expecting on a random midweek day in June 2 years later was to find almost 18 hours of session work and mix downs to be thrust upon the internet.
