In a recent Variety article, the work of Pasek & Paul in the movie musical THE GREATEST SHOWMAN is discussed. It seems Variety was given a chance to listen to the musical score or parts of it.
Interestingly, Pasek & Paul have been working on the score for the last 3 years-and-a-half, even ahead of their work in La La Land and Dear Evan Hansen. Also of interest is the type of musical score written for the movie, supposedly adding a more contemporary tone to it.
