"Nude" explores themes of suburban ennui, crushing boredom, and unfulfilling lives, with its lyrics addressing the emptiness that can pervade everyday existence. The song's title comes from an early chorus line, "What do you look like when you're nude?", hinting at a stripping away of pretenses. This track from the 2007 album In Rainbows was a long-gestating piece, with earlier versions dating back to the OK Computer sessions, finally finding its form with a new bassline that transformed its rhythmic flow. It plays like a graceful and sorrowful observation of lives lived without true connection or purpose.
