Berberian Sound Studio trailer

I've been seeing a lot of reviews lately for the soundtrack to this film. I missed it at TIFF but it holds particular interest for me as the main character is a sound designer on a film. Looks like it might have some meta-type elements, you know, like the film the character is working on actually is the film we're watching type stuff.

Can't find a DVD release for it, I'll just have to keep my eyes open.
