MUMBAI: Academy Award winning composer and living legend, AR Rahman, has been caught up with adding the final touches to his soundtrack for the Hollywood film 'Million Dollar Arm'.

According to a post on his Facebook page, Rahman seems to have collaborated with the likes of Iggy (Pop), Kendrick Lamar (in the movie only), KT Tunstall, Sukhwinder Singh and Raghav Mathur amongst others, for the soundtrack for the film. He has also worked on “lots of underscore”, which was also mentioned in the post.

Rahman also mentioned that the soundtrack will have a surprise Tamil song from his '90s collection, which will play during the end credits. The track is said to have vocals by KS Chithra and Unnikrishnan. The recording of the score was completed by February 2014 and the album is scheduled to release on 13 May 2014.
