He had an inclination towards singing from an extremely young age and was constantly persuaded by his ustad to graft in his raags and perform on stage. Manak’s father was a singer himself. Kuldeep left Bathinda and went to Ludhiana to pursue his career as a singer and started singing with a singer duo. When they came to Delhi, a music company official spotted Manak and asked him to record a song. This record was a runaway success and changed his life. In the late 1970s and early 1980s Manak was generally regarded as the best Punjabi singer in the world. His high pitched strong voice was unique, and instantly recognizable. In his early career he became the baadshah of kaliyan.
