Radiohead have announced the upcoming arrival of a new music video for the previously-unreleased song “If You Say The Word”. Originally recorded in the early 2000s, the song was shared by the band earlier this month, as part of its Kid A Mnesia reissue, a new triple album that commemorates 20 years of Kid A and Amnesiac.

Featuring reissues of the two albums (released in 2000 and 2001, respectively), the collection will also include Kid Amnesiae, a record of unreleased rarities from the era, including “If You Say The Word”. On Instagram, the band describes Kid Amnesiae as: “a memory palace of half-remembered, half-forgotten sessions & unreleased material.”

Directed by Kasper Häggström, the full music video for “If You Say The Word” is set to arrive on Thursday (September 23) at 3pm UK time. Watch the teaser below.

Earlier this month, Radiohead also teased a mysterious new digital project while speaking at Sony’s PlayStation Showcase. The group described the “Kid A Mnesia Exhibition” as an “upside-down digital/analog universe” based on “original artwork” and “multi-tracks” by frontman Thom Yorke and artist Stanley Donwood.

Donwood’s haunting, apocalyptic artworks for Radiohead’s Kid A were also recently picked up for an exhibition at the London headquarters of Christie’s, ahead of the sale of six large-scale paintings. Take a closer look here, and watch the “If You Say The Word” teaser below.
