Written in the wake of Mumbai, India, terror attacks, a song inspired by the lives of fallen Chabad-Lubavitch emissaries Rabbi Gavriel and Rivka Holtzberg has experienced a new popularity after a video production of the recording went viral on the Internet.

“Fallen Angels” was composed by Moshe Kravitsky, while its video features images from the Mumbai Chabad House and other photos compiled by Brooklyn-based Rabbi Levi Teldon.

“The lyrics come from the heart,” says Kravitsky. “Everyone is able to respond to the Mumbai tragedy in their unique way, and I feel people can relate to the Holtzbergs’ holy lives through the message in the music.”
