Tamil auteur Mani Ratnam's violent tale of a family blood feud over a multinational criminal empire finds his longtime collaborator and filmi music legend A. R. Rahman craft a complementary soundtrack laced with menace and passion. The indomitably sunny and catchy love song "Mazhai Kuruvi" segues into a furious flurry of Sunitha Sarathy vocals on the energetic "Sevandhu Pochu Nenju". Meanwhile, the haunting choral chanting of "Madura Marikozhundhae", with its understated tapestry of whirring looped voices and droning tambura, is one of Rahman's most uniquely original works.
