Kaala music director Santhosh Narayanan debuted in the film industry with Pa Ranjith's movie Attakathi. Today the composer-director duo have succeeded yet again with brilliant music for Rajinikanth's Kaala. Santhosh reveals how Thootukudi shooting had him rework the back ground score of the climax portions and why Kaala is the most women centric film that he has worked on. The composer is now looking forward to the release of his next film Pariyerum Perumal, which is produced by Pa Ranjith.
