After Hum Tum (the last Vital Signs album), Rohail Hyatt and Shoaib Mansoor went their separate ways. But now, Rohail Hyatt has been roped in by Shoaib to do the background score of his debut directorial venture, Khuda Key Liye. This will be the first time that numero uno producer Rohail Hyatt will do a Pakistani film score. Even though, other artists will be featured on the soundtrack, Rohail feels the background score will give him enough scope for 'creative expression'. Work on the soundtrack has already begun at Rohail's studio in Karachi. It is still unclear when the film will be released but with the huge star cast (Shaan, Iman Ali, Fawad Afzal Khan), it looks like Saqib Malik's Ajnabi Shehr Mein is in for some tough competition.
