Sonu Nigam was born on 30th July 1973 to Mr. Agam Kumar Nigam and Mrs. Shobha Nigam in the city of Faridabad, Haryana. Sonu performed on stage for the very first time at the age of three and a half when he joined his father on stage to sing Late Mohammed Rafi's popular song "Kya Hua Tera Vaada" from the film Hum Kisise Kam Nahin. Then on, he accompanied his father for his various singing assignments. In his teenage years, he participated in several music competitions and won them all. During one of these competitions he was judged by the renowned music director of Bollywood, Anu Malik who pronounced him the winner and also gave a word of encouragement to work towards being a playback singer in Bollywood. He moved to Mumbai with his father on 23rd September 1991 to begin his singing career. His initial years in Mumbai proved to be a struggle, and he started by singing covers of Mohammad Rafi songs, mainly for the "Rafi Ki Yaadein" album series. These albums contributed to his label for some time as a "Rafi clone." His first movie song as a playback singer was in the movie, "Janum" (1990), which was never officially released. He got a break as a playback singer in Gulshan Kumar's movie, "Aaja Meri Jaan"(1993). He then sang the song, "Accha Sila Diya", for the album "Bewafa Sanam" (1995), which went on to become a hit and gave him the recognition as an established playback singer!
