Starring Dhanush and Parvathy, 'Mariyaan' is a story of survival. Based on the fiction of a fisherman caught up in the Sudan oil wells, the story revolves around five important emotions - love, separation, pain, confidence and rise. We hear that it was not only Dhanush, but also the music director AR Rahman, who has displayed these emotions. Rahman is said to have composed a beautiful album, containing one song for each of the emotions. The best of the lot is said to be a song where a galore of emotions has been brought by Rahman, to fit the few minutes of the song. According to a source close to the team, the over all effect reminds one of Bharat Bala-AR Rahman rapport in the world famous 'Vande Maataram'.
