Versatile actor Farhan Akhtar, who made his acting debut with the musical film 'Rock On!!', recently performed at the Independence Rock fest held in Mumbai. He feels that rock music is what keeps the maximum city of Mumbai alive. 

He seems to be right as the cosmopolitan is a melting pot of different cultures and rock music keeps it pulsating. The 'Dil Chahta Hai' helmer is a die-hard rock'n'roll fan and was thrilled to perform along with Indian rock band 'Parikrama' at the fest which returned to Mumbai after a hiatus of nine years.
