When you see Sukhwinder Singh, it's hard to believe that the torrential voice behind "Chaiyya Chaiyya" could issue from such an unassuming man. But it does, and despite industry efforts to pigeonhole him as a folk singer, Singh has been finding lots of work since his award-winning performance for A.R. Rahman's Dil Se (1998). World audiences were introduced to Singh when he performed songs for Deepa Mehta's 1947 Earth (1999). He later sang the inimitable "Aaj Mera Jee Kardaa" in Meera Nair's 2001 film Monsoon Wedding.
