Audio launches seem to grab the lime light enjoyed by premieres these days. Some of the audio launches held recently had turned out to be so colourful and extravagant to rob the attention of even the world media. The latest in the row will be Sundar C's Nagaram Marupakkam. The flick is produced by his wife and actress Kushboo. The audio of the flick will be launched on September 4, 2010 by Chief Minister M Karunanidhi and Kollywood actor Kamal Hasan. A glossy cultural event will follow the show on Sept 4th.
