I have seen this movie yesterday and I think this is a average movie. Zubaan is a 2015 Indian musical drama film written and directed by Mozez Singh, starring Vicky kaushal and Sara jane Dias with music composed by Ashutosh Pathak.
The film is the coming of age story of a young boy vicky kaushal who loses his faith and develops a fear of music & his journey in fighting that fear and thus finding himself. I recommend you to see this movie if you have time to enjoy.
