Radiohead has never shied away from arty and elaborate “special edition” versions of its albums, which normally ship to fans with unique artwork and limited vinyl. But Tuesday’s collector’s item release of the OK Computer 20th anniversary edition, priced at a whopping $130/£100, shipped with that most hipster of audio formats included: a C90 audio cassette.

And if you’re wondering whether Radiohead’s bizarre, technology-theorizing landmark album would pack something computer-related into that cassette tape, you might want to dig up your old Sinclair ZX Spectrum cassette drive.
