• Speaking about the song and the Barbara Barbara album to Consequence of Sound, Underworld's Karl Hyde said: "This is a record that's split into two sections, with a divider in the middle, 'Santiago Cuatro.' They are all quintessentially Underworld.
  
  For me, what happens in those first two tracks, 'I Exhale' and 'If Rah,' is I see those visually. I always see those tracks as someone laying down the Eiffel Tower on its side and cutting it up into these shards of rhythmic steel. And when you get to this moment of 'Santiago Cuatro,' you can step back, take a moment, then come through this doorway and travel around on this vast, sunlit plane."
• The album title came from Rick Smith's father, who passed away in 2015. Karl Hyde told Spin: "Toward the end of his life, Rick's father was talking to Rick's mother - her name is Barbara - reassuring her that everything's going to be okay. That they had a bright future. 'Barbara, Barbara, we face a shining future.' To reassure her. When I heard Rick say that... I just said to him, 'That's the title.'
  
  I don't think he realized the extent to which I wasn't going to back down. He came up with a few more titles, and I just sort of [responded,] 'Are you mad? Why are you wasting your time talking to me about this? That's the title!'"
