Here’s an interesting look into the sound design process of Darren Aronofsky’s latest feature, Black Swan.

A dark and twisted tale of a young dancer (Natalie Portman) and her descent into madness during rehearsals for a new version of the classic ballet Swan Lake, Craig Henighan (Aronofsky’s sound designer since Requiem for a Dream), talks about some of the techniques used to create Portman’s characters’ fractured state of mind.

It’s interesting to note the subtlety in sound which Henighan brings to many of the films’ set pieces, in particular the nightclub scene, where his creepy layering of voices and noises are interwoven with the thunderous and overpowering Chemical Brothers song, and yet are still able to help create an unsettling and ominous mood.

You can see (or rather hear) the unique soundscape Henighan has created when the film is released on the 21 January.
