The producers of RS Infotainment have always followed an unique way of releasing their music. It started off with 'Vinnaithaandi Varuvaaya' that had a festive like audio launch. Now, the same trait has followed in 'Ko' that had its audio launch last evening at Image Auditorium in MRC Nagar. It wasn't like an usual affair as there were no special chief guests and their speeches. It was just about performance by singers and actors that created huge waves of applause from the special invitees. The song performance received more laurels as the songs were fantabulous. The audio CD was launched by none other than the photo journalists themselves since the film revolves around protagonist who plays the role with same profession. Filmmaker Priyadarshan and Udhayanidhi Stalin were present throughout the show along with Jeeva, Karthika, Ajmal and Pia Bajpayee along with other crewmembers.
