Nice observation, the entire film communicates with the music and sound. Without the barrier of language and age, every one can enjoy every second of the movie.In the film Pushpaka vimana, Kamal Haasan playing a tramp who takes a rich man's identity after abducting him and imprisons him in his noisy shabby lodge finds the quiet comfy hotel room of the rich guy disorderly. A genius audiophile inside him finds the solution - he records the noise around his former place of residence and plays it to get some sleep finally! Not a bad audiophille level hack!
Kamal hassan gives importance to sound a lot. Some of his films were mixed by oscar winning team including whiplash.
Kuruthipunal was the first of its kind implementation of surround sound dolby back in mid 90s for which it even went to oscar selection (not nomination though). Ofcourse it was also live sound recording experimentation to add to the zeitgeist it gives in retrospect to mid 90s era.
