She was born in Loha village of in Tahsil Ratangarh, Rajasthan to a Banjara (Gypsy) family about 1947. Her family moved to Pakistan during the partition of India soon afterwards. She says she does not have any training in classical music. In 2004 her rendition of Ashkan Di Gali Vich Mukaam De Gaya was in the top ten of the Indian charts.
Reshma once said in an interview, “I was born in a family of saudagars in Rajasthan in a small settlement called Bikaner. I don’t know the year I was born but I was told that I was brought to Pakistan when I was a few months old in 1947. My family would take camels from Bikaner and sell them in other areas, and bring back goats and cows from elsewhere to sell at home. I belong to a huge clan of gypsies. We were forever travelling around. Though a lot of us have now settled and taken up permanent residences in Lahore and Karachi, whenever we feel restless we pack our bags and move on.”
