Song: "What If"
"'What If' was the first track that we finished for Odeon. The song's basic idea – 'what if this was not the case' – can serve as a layout for the whole album: what if noise was a song? What if the sound of the sea was a symphony? What if the ears could listen?" Tosca's Rupert Hubert explains to Rolling Stone. "The vocals of Belgian singer Sarah Carlier are an instrument like any other instrument on the track, as we always like to do. Every Tosca track is an architecture of sound, and the time of the clock turning into groove-time."
