A series of posters appearing worldwide with a theme of "more fear" and "1997 2017" at the bottom, in the style of "Fitter Happier," sparked rumors that Radiohead were on the verge of announcing something having to do with the 20th anniversary of OK Computer. Yesterday (5/1), a year to the day after Radiohead began to delete their internet presence leading up to the release of A Moon Shaped Pool, Radiohead released a mysterious teaser video featuring a child's voice reciting the lyrics to "Climbing Up the Walls." Today, Radiohead announced the 20th anniversary edition of OK Computer, called OKNOTOK. The reissue features the original 12-track album, remastered from the original analogue tapes, as well as three unreleased tracks ("I Promise," "Man of War," and "Lift") and eight b-sides, six of which also appeared on the 1998 Airbag/How Am I Driving? EP. See the full tracklist below.

The special boxed edition of OKNOTOK contains a hardcover book with never before seen artwork, full lyrics, a notebook of 104 pages from Thom Yorke's library of notes, a sketchbook with Stanley Donwood and Yorke's "preparatory work," and a casette mix tape taken from OK Coputer session archives and demo tapes. The boxed edition begins shipping in July. There are more regular vinyl, CD, and digital editions that are available from June 23.

Radiohead recently played Coachella and have shows coming up in June and July, including a show in Israel, which some artists have protested.
