Fire leaks from the mountaintops. That is the first thing the eye catches on Kid A: two summits in the upper-left venting orange flame and black smoke into a sky that burns from deep brown down to a livid red horizon. Below, a jagged white range crowds the frame, its peaks sharpened into fangs, the snow stained with streaks of blue and flecks of black. Toward the foreground the whole picture seems to glitch and smear, pixels dragged downward like a signal breaking up, as if the landscape itself were dissolving in front of you.

Those barbed triangles are no accident. Stanley Donwood, who has made every Radiohead cover since 1994, built the Kid A images as huge canvases, painting with knives and sticks before photographing them and pulling the results apart in Photoshop. He called the mountains 'landscapes of power,' shapes meant to carry cataclysmic force. Across the paintings of this era the same menacing triangular motif keeps returning, surfacing as barbed peaks, as trees, as fangs in stark terrain, drawing on German expressionism for its sense of dread.

The spark behind the snow was real and specific. Donwood traced the idea to a newspaper photograph from the Kosovo war: roughly a square metre of snow filled with the detritus of war, an image that upset him in a way that war never had before. That fragment of frozen ground bloomed into a whole frozen world. The range also carried his alarm about climate change and melting ice caps, the white peaks doubling as a warning about glaciers under threat.

Donwood did not work alone. The artwork came from him and Thom Yorke together, Yorke credited under aliases like 'Tchock' and 'Dr. Tchock' whenever he turned to the band's visuals. The two had met as art students at the University of Exeter, a partnership that has run the length of Radiohead's career. For Kid A they worked inside the band's converted-barn studio in Oxfordshire, surrounded by the album as it was written and recorded, the paintings absorbing the sound being made in the next room.

The title itself arrived almost by accident. Late one night the pair had made too many versions of the front cover, each with different pictures and titles set in different typefaces. Unable to choose, they taped them all to the kitchen cupboards and the fridge and went to bed, hoping the right one would be obvious by morning. It was. The survivor reads the way you see it now: 'RADIOHEAD' small in red, and 'KID A' stamped huge in rough white capitals, their edges torn and uneven like letters cut from paper rather than typed.

The danger ran deeper than the sleeve. The red of the swimming pool printed on the spine and disc, inspired by the graphic novel 'Brought to Light,' stood for danger and broken expectations. Some early CD pressings hid a book of artwork beneath the disc tray, packed with ire: an image of then prime minister Tony Blair, and another spelling out ecological disaster through information on melting glaciers, the same anxiety driving the cover's burning mountains.

Released in 2000 on Parlophone, with a US edition on Capitol, the album landed across rock and electronic territory, what listeners later filed under indie electronic and experimental rock. The paintings outlived the record. Made between 1999 and 2001 in the same burst as the follow-up Amnesiac (whose special edition won Donwood and Yorke the 2002 Grammy for Best Recording Package), six of the large-scale Kid A canvases went on display in October 2021 at Christie's London, in an exhibition the two co-curated called 'How to Disappear Completely,' offered at auction with estimates starting at £10,000. The flames on the sleeve, it turns out, were painted to last.
