Harbhajan Mann began singing in 1980-81 and as an amateur who used to perform in local shows for the Asian community while in his school in Canada. His aspirations to sing professionally were sparked when he studied music from his first guru, Karnail Singh.
His first professional break came to him in 1992 while he was still in Canada with the release of Chithiye Nee Chithiye. This track became a successful with the target audiences in Punjab. After the success of the single Chithiye Nee Chithiye in India, Harbhajan realized that the industry for Punjabi music was too limited in Canada. Harbhajan returned to Punjab to record his albums. Harbhajan's melodious voice was still relatively undiscovered until 1999. With the help of India MTV and some extra promotions from T-Series, Mann's 1999 album, "Oye Hoye", became an explosive hit. His Punjabi-pop style soon attracted audiences from all over India. Singing was not only a Passion inside him but he started giving his voice to the actors as he turned into a Playback Singer and an Actor. Harbhajan Mann has became a prominent figure in the revitalisation of Punjabi cinema. He has starred and produced in seven movies, namely "Ji Aayan Nu", "Asa Nu Mann Watna Da", "Dil Apna Punjabi", "Mitti Wajaan Mardi", "Mera Pind, My home", "Jag Jeondiyan De Mele" and his most recent movie "Heer Ranjha". He has also produced the soundtrack albums for his movies.
