Rockstar is directed by Imtiaz Ali and stars Ranbir Kapoor in the lead. It has been produced by Shree Ashtavinayak Cine Vision and Eros International.

While working on Saadda Haq, Rahman, Imtiaz, Irshad & Mohit Chauhan agreed that they needed a lead guitarist to justify the tempo and the lyrics of the song. A source says, “While Rahman and Imtiaz had shortlisted Indian and international musicians, they had Orianthi on top of their list.”

Rahman checked with his agent in LA and met up with Orianthi during one of his visits there. He made her listen to the rough track and she loved it.

“The director had a discussion with Orianthi on Skype; briefing her about the film’s story and the song’s relevance. Orianthi who was sitting with Rahman in LA played some tunes that she felt could work well for the song. Imtiaz & Rahman loved it and Orianthi was on board,” the source adds.

A few days later, Rahman recorded Orianthi playing the guitar for Saadda Haq in his LA studio. The process took six hours, while Imtiaz witnessed the session through Skype.
