New Delhi, Oct 25 Bollywood actor and filmmaker Farhan Akhtar rocked the audience with his songs at a music concert here last evening.

Farhan sang songs from 'Rock On' that had been a huge hit after its release and had made him into a youth icon.

The enterprising filmmaker, who has made quite a mark with his earlier films, is all set to floor the audience with his forthcoming venture 'Karthik Calling Karthik'.

The film has an unusual theme of a man receiving phone calls from none but himself.

"We've tried our best to present a new kind of story in a new kind of way. The director, Vijay Lalwani, it is his first film," said Akhtar.

'Karthik Calling Karthik' is slated to hit the screen across India in 2010. (ANI)
