No country for old men is one of the best examples. I love that film I agree with georgi.m with the coens' approach to film. Another film maker who has an adrimable attitude is George Lucas I mean the fact that his sound company is named after his first feature film speaks for itself.
Also the 90's psycho remake was actually pretty good in terms of the sound. Lost Highway was very good as well. Fantastic plaent or la planette savage was great if you take the same attitude as I do in term of the music BEING the sound in a film as well.On that topic, a short film called "copy shop" is a very good example of that synchresis that was mentioned http://www.youtube.com/watch?v=EaLvuAvazDI.
