Puratchi Thalapathy Vishal is gearing up for the release of his upcoming action entertainer 'Rathnam', directed by Hari. While the film is slated to hit the screens on April 26 as a Summer treat, the makers unveiled the first single from the album yesterday.

The entire team including Vishal and director Hari launched the first single at the cultural program in VIT College, Chennai. Devi Sri Prasad has composed and sung the song, "Don't Worry Machi", a peppy upbeat opening song with lyrics by Viveka. Vishal and Yogi Babu's dance moves make this song more enjoyable. This song is going viral now.

'Rathnam' stars Vishal, Priya Bhavani Shankar, Samuthirakani, Yogi Babu, Gautham Vasudev Menon and others. The shooting is over and the post-production is going on in full swing now. The technical team comprises M Sukumar as the cinematographer, T S Jay as the editor and P V Balaji as the art director with stunts by Kanal Kannan, Peter Hein, Dhilip Subbrayan and Vicky.
