Radiohead album hides an app that only runs on an ’80s computer

While the vast majority of the 90-minute tape houses a collection of rare demos from the band, the last two minutes treat listeners to a bizarre high-pitched frequency. Quickly identified by Redditors as the grating greeting of the ZX Spectrum, one passionate YouTuber has cleverly EQ’d those digital squawks and squeaks to perfectly match the aging computer’s audio language.

Running those EQ’d files through a ZX Spectrum emulator, the software pops up with the names of all the band members, dating the software back to the 19^th December 1996. After the introduction, all that hard work is finally rewarded with some scrolling text and a seemingly random arrangement of bloops and bleeps. It’s a bizarre but very cool little Easter egg, and thanks to YouTuber OooSLAJEREKooO you can save yourself some time and check out a video of the whole thing below.
