Kavitha Krishnamurthy married Dr. L. Subramaniam in Bangalore on November 11 1999. The surprise wedding took place in Bangalore in the presence of just 25 relatives. The world came to know it only on November 15 1999. Dr. L. Subramaniam has three children from his earlier marriage and she accepted them as her own children. Their daughter Seetha is a law graduate and is currently working on an English album. Narayanan, the middle one is a qualified doctor and loves music while Ambi, the youngest is a violinist. She says that they chose to live in Bangalore as her husband likes the city a lot and decided to make it his base. She would ideally prefer to work out of Bangalore but feels the need to be with her family.
In 1971, when she was still a child, she sang her first film song which happened to be a Bengali duet with renowned playback singer Ms. Lata Mangeshkar that was conducted by the music director Hemant Kumar. Kavita moved to Bombay with her aunt to try her luck as a playback singer. She has attended the St. Xavier's College in Bombay and acquired a degree in Economics.
The music director and singer Manna Dey spotted her talent and employed her to sing ad jingles. Her aunt introduced her to Mrs. Jaya Chakravarthy, the late. mother of actress Hema Malini who later took the initiative of meeting Laxmikant (of the Laxmikant-Pyarelal) fame in late 1976.
Impressed by Kavitha's skills, Laxmikant offered her work as a dubbing artiste cutting demos of songs intended for playback singers like Lata Mangeshkar and Asha Bhosle. In the 1980s "Kaahe Ko Byaahi" was the first song that was featured in a film using her own voice. In 1985, she landed her with her first major hit, "Tumse Milkar Na Jaane Kyon". In her struggle phase, Laxmikant-Pyarelal backed her so strongly that she was labelled as someone from the Lakshmikant-Pyarelal camp. After the success of "Tumse Milkar Na Jaane Kyon", it opened up opportunities for her outside the Laxmikant-Pyarelal camp, with which she had faithfully worked up to that point.
In 1994, when R D Burman staged a mind-blowing comeback with 1942: A Love Story, he selected Kavitha to sing for him. The music went on to be a superhit, unfortunately, Panchamda passed away. She went on to become one of the most popular female playback singers after Lata Mangeshkar and Asha Bhosle. During the 1990s, she worked with some of the best music directors of India including Anu Malik, Jatin-Lalit, Nadeem-Shravan, Ismail Darbar, A R Rahman.
