Director Farhan Akhtar, who makes his acting and singing debut with Rock On, says his crooning for the film was essential to make the character authentic.

Releasing this Friday, the film narrates the story of four friends who put together a rock band but fail to make it a success. Years later, fate brings them back together to relive their cherished dream from where they had left off.

Other actors in the film include Arjun Rampal, Shahana Goswami, Luke Kenny, Koel Puri and Prachi Desai.

Farhan, who has sung six out of nine songs in the film, said that him singing for the lead vocalist’s character was their way of showing their sincerity towards the project.

The actor-director, who has made films like Dil Chahta Hai and Lakshya, said he has been inclined towards music much before the film came along.

As an actor, Farhan would be next seen in Luck by Chance and The Fakir of Venice. And as a director he will helm the shooting of Voice from the Sky later this year.
