A challenging record that went against the grain, a profound reform of the writing method, a total redefinition of the notion of a group, and a significant departure from the song format. Don't bother looking for a single here, there isn't one. In this long maze of experimental sounds and structures, Radiohead broke the verse-chorus mold, melted it down into a series of repetitive sonic dissertations that eventually collide in harmonic crossroads where a semblance of a chorus takes shape. Inspired by the musical theorems of electronic music (Aphex Twin and Boards of Canada), the band abandons rock to flirt with a cleverly written musical happening, generating sounds and sensations rather than frank emotion. A demanding and hostile album that only reveals its secret charms after long hours of patience and multiple listens on repeat.
