This haunting piano ballad finds Yorke inviting us to dive into 'a clear lake', and 'No one gets hurt' he promises.
The song is, according to Rolling Stone writer Will Hermes, 'about washing yourself clean in a world of dirty water'.
A cello led string section enters later in the track. The strings are performed by The London Telefilmonic Orchestra.
The song also features long, mournful horn trills, making it the most horn-filled Radiohead song since Amnesiac's 'Life In a Glasshouse'.
