• This is a song from Sonic Highways, an album containing eight songs, each laid down in a different US city. The band would start recording in the studio during the day at each location and then in the evenings, Dave Grohl would interview various local musicians. By day four or five the Foo Fighters frontman would pour over the interview transcripts and outline the songs he wanted to write. Grohl explained to Jimmy Fallon, "I would pick out words, phrases and sentences from the interviews."
  
  He added: "It was meant to represent that whole week we had been there by telling the stories of the people I had talked to."
  
  This track was laid down at Inner Ear Studios, Arlington, Washington DC.
