Darren Aronofsky is a masterful filmmaker, and The Fountain is no exception, but I can’t image what his films would be like without the emotional scoring of Clint Mansell.
Death is the Road to Awe pretty much encompasses the depth of the entire score and slowly builds in intensity towards the film’s climax.
