It is supposed that for a few, music runs in their very genes. The same holds true for Rani as well, a powerful performer and a versatile Bollywood playback singer and instrumentalist, born to the renowned Hazarika music dynasty of Assam. Starting off at a tender age of three under the mentorship of her father Late Rose Hazarika, music has meant everything to her since then. Also, her uncle Dillu Hazarika is a famous music director. In her sixth grade, she started singing professionally in various stage shows and by the time she reached the eighth grade she was already a recording artiste. Apart from being a musician she is a rhythmist and has recorded over 1000 songs in different South Asian languages such as Hindi, Bengali, Assamese, Oriya, Bhojpuri, Maithali and Kasmiri.

A graduate in B.Music (Vocals) from Bhatkhande Lucknow Gharana, her path of music was not quite smooth. Having three sisters who were exceptionally talented in singing, was a challenge for her father in itself, in helping all of them get ahead. Although stepping foot in Mumbai on 2006 was much like a dream come true for her, having no acquaintances there proved equally tough.
