Chennai: The soundtrack of superstar Rajinikanth-starrer Tamil action-drama "Kabali" was officially unveiled on Sunday. The Santhosh Narayanan-composed album features five songs, and of them "Neruppu Da" and "Ulagam Oruvanukka" have become instant chartbusters within a few hours of release. Featuring voices of a host of young and promising singers, "Kabali" is the first Rajinikanth-starrer in over two decades that doesn't feature an S.P. Balasubrahmanyam number. For many years, it has been a tradition as well as a sentiment to make Balasubrahmanyam sing the title track in a Rajinikanth's film. However, in "Kabali", the title track "Ulagam Oruvanukka" features voices of Ananthu, Santhosh Narayanan, Gana Bala and Roshan Jamrock. The album also features two soulful renditions -- "Maya Nadhi" and "Vaanam Parthen" -- which are melancholic yet poignant. The makers had planned to release the second teaser of the film on Sunday. However, the same has been postponed by a few days. Directed by Pa. Ranjith, "Kabali" features Rajinikanth as a don, and he will be featuring in two different avatars. The film, which is slated for July 15 release, also features Radhika Apte, Kalaiarasan, Dinesh, Dhansikaa, Kishore and Winston Chao.
