Sonakshi Sinha hits some notes for Akira's promotional video

After making a singing debut with her single 'Ishqaholic', Sonakshi Sinha has lent voice for a promotional song of her upcoming film 'Akira'. In a recent interview, the actress said going behind the mike for the film was a very spur of the moment thing. Talking about the spirit of the song, Sonakshi said the song is about rage, about how a woman will not stay silent and will fight back. 'Akira' is directed by A.R. Murugadoss, who had previously directed Sonakshi in the film 'Holiday', which was a success at the box office. The film will release on September 2.
