This new film by AR Rahaman, is all about music, and how musicians and their bands perform in a musical concert. This is the first time a film as such has been released in Kollywood. One Heart: AR Rahman's Concert Film focuses on Rahman's United States tour, which was a grand success. 

We have seen AR Rahman conquer the stage with his magical music and voice. But we are completely unaware about what happens before and after he gets on and off the stage. Hence the film features; on how backstage works, how live concerts are coordinated and how the band gears up before a concert. In this 87-minute film, we will see a compilation of the best songs of AR Rahman's compositions. We will also see him talk passionately about music, his crew and how technology works. 

This is not a regular film or a biopic about Rahman, it's a totally new musical experience. With glimpses of his performances from his live concert shows, giving us an impression of actually watching a live concert. It is said that if we watch this movie in theaters which has  Dolby Atmos Technologies, then we can really enjoy the film. 

In short, One Heart: AR Rahman's Concert Film, is a new experience.
