• This is a track from Radiohead's The King of Limbs - From the Basement concert album. It was released as a single on 12-inch vinyl in the UK, Europe and Japan on 16 April 2011 for Record Store Day. The song was released on the same format in the United States and Canada on June 14, 2011.
• The song was debuted as a solo Thom Yorke performance on June 6, 2008 at Malahide Castle, Dublin, and performed during the singer's initial Atoms for Peace warm up shows in 2009, but was later fleshed out during the King of Limbs sessions and finished in March 2011. Before playing the song at Radiohead's March 10, 2012 show in Kansas City, Yorke introduced it by saying: "Basically, you probably don't know it, but you will once we've finished it, in 5 minutes."
• During a Reddit AMA Q&A in February 2013, Yorke was asked how he decided whether something is a Radiohead or Atoms for Peace song. He replied: "Its a grey area. getting greyer. obviously depends on who is being sampled. " Yorke added that this was always going to be a Radiohead song, but at the time he needed it to flesh out the AFP set lists.
