Half of Bombay’s population lives in the slums. Children who live there have never seen their hopes and dreams fulfilled…until now.

The Bombay Chamber Orchestra set out to find the musical children, the ones who will never be anything due to social status. The Orchestra pulled them out of the slums for a one-night-only event: The Sound of Mumbai: A Musical. The kids and the Orchestra put together an adaptation of the Rogers and Hammerstein musical The Sound of Music and performed it in Mumbai’s National Center for Performing Arts, normally inaccessible to the poor.

Sarah McCarthy directed the documentary on the spectacle. The Sound of Mumbai will debut on HBO2 on November 23rd. In addition to simply filming the event, McCarthy also uses the documentary to highlight the long-lasting, international appeal of The Sound of Music.

The Sound of Mumbai mostly focuses on 11-year-old Ashish, the star of the musical. In doing this show, Ashish hoped to find a patron to fund his education, something that would have been impossible for him otherwise. It will also feature Mangesh, Ashish’s jealous best friend, and Kimberly, a higher-class girl whose affections Ashish hopes to win.

Along with The Sound of Mumbai, HBO and HBO2 are featuring three other documentaries focusing on India this month. They are Pink Saris, following the life of Sampat Pal, leader of the Gubali Gang; Marathon Boy, about a four-year-old marathon runner whose dreams were at his fingertips and then shattered; and The Bengali Detective, the story of a man who works as both an investigator and a dancer.
