Sathyaraj is an established and an old fashioned music director in the industry. He is loved and respected for his works and is termed as the greatest musician of our times. SJ Surya who works as an assistant under Sathyaraj gets an opportunity to compose music for a small time film. When he seeks permission from Sathyaraj to go ahead with his first venture as a music director, Sathyaraj doesn't oppose the idea as he wouldn't have imagined even in his wildest dream that one day SJ Surya would surpass him in the musical world.
When Surya uses new techniques with the help of computer and softwares, his music gets the attention of all music lovers. Due to the freshness and modernity his music possesses, he gradually becomes the most sought after musician and finally overtakes Sathyaraj. SJ Surya becomes the number one musician and also builds his own studio. Meanwhile he falls in love with Sulagna Panigrahi(much before he becomes famous) and also marries her.
When it seems everything he touches turns to gold, Sathyaraj displays his true colors. To get his glory back, Sathyaraj does whatever it takes to label SJ Surya unfit to compose music. Can SJ Surya bounce back despite his new and unwanted status forms the rest of the story.
Isai movie audio launched on Nov 10th, 2014. Music composed by S J Surya for the first time.
The project was announced by S. J. Surya in 2004 shortly after the release of New, when he revealed that A. R. Rahman would also collaborate for three of his future ventures titled Anbulla Nanbane, Aezhumazhai vs Chitra with Silambarasan and Asin and Isai. While the first film released as Anbe Aaruyire in 2005, the latter two failed to progress.
In January 2006, the film was reported to be back under way with either S. S. Chakravarthy or Navodaya Appachan being producer and it was suggested that the film would be about a "cunning assistant music director comes to the top". Other reports had also suggested that the film told the tale of the tensions between South Indian musicians Ilaiyaraaja and A. R. Rahman.
In 2011, Surya announced that the film would restart and he would compose the film himself, describing it as a "musical".
In May 2012, the film's first look posters were finally revealed, with Sulagna Panigrahi, an Oriya and Indian television and film actress in the leading role under the new name Savithri, who had made her Bollywood debut in the 2011 thriller Murder 2. Sathyaraj was signed on to play the role, with Surya confirming that the film would be based on a tiff between two music composers.
