Fans have recently noticed that Radiohead was being playful with a tease of something planned for their 20th anniversary of the release of their seminal OK Computer. Today we finally know what that was all about: it is a box set and it’s magnificent.

That tweet would have gotten to you this site:

Once there, you can see that they’re now taking the 12 tracks from the album and adding some original B-sides and some unreleased stuff, all nicely remastered for the new box set. Supposedly we’ll see them shipping in July.

Check out the track list and bigger description below:

Rescued from defunct formats, prised from dark cupboards and brought to light after two decades in cold storage… OK COMPUTER: the original twelve track album, three unreleased tracks and eight B-sides, all newly remastered from the original analogue tapes*.

Inside a black box emblazoned with a dark image of a burned copy of OK COMPUTER are three heavyweight 180 gram black 12″ vinyl records and a hardcover book containing more than 30 artworks, many of which have never been seen before except by us, and full lyrics to all the tracks except the ones that haven’t really got any lyrics.

Under this weighty tome are yet more surprises: a notebook containing 104 pages from Thom Yorke’s library of scrawled notes of the time, a sketchbook containing 48 pages of Donwood and Tchock’s ‘preparatory work’ and a C90 cassette mix tape compiled by us, taken from OK COMPUTER session archives and demo tapes.

To avoid accusations of wilful obscurity, a 320k MP3, 16- or 24-bit WAV download of 23 tracks will be available to you on 23rd June and a download of the cassette will be inside the box.
