Music Maestro AR Rahman had joined hands with Ideal Entertainment, a Canada based company, for a three film deal a while ago.

And of the three films in the pipeline, One Heart is of special interest to his fans as it will be based on Rahman's concert experiences.

According to reports, the film will feature never before seen footage of Rahman and his band performing their most loved songs. It will also feature interviews with the reticent maestro where he shares his thoughts on performing onstage, how he chose his band which toured with him across America, and his immense popularity in India.

One Heart is expected to release in April and the poster shows Rahman at the piano with his ten member band seated on it.

Rahman has had a pleasant association with Canada so far - he even has a street named after him in the country, and was invited to move there by one of the Canadian mayors. Rahman had politely declined the invitation and said that he was happy at home in Tamil Nadu.

Kaatru Veliyidai, Rahman's latest with Mani Ratnam, is also due for release in April, making it a double bonanza month for his fans.

The other two films for which Rahman will be teaming up with Ideal Entertainment are Le Musk and 99 Songs.
