She was born in the Mordvinian village of Gorki in Tatarstan. Her father, Nikita Mikhailovich Kadyshev worked for the railways, her mother, Anna Andreyevna stayed at home with five daughters. Kadysheva was 10 years old when her mother died, and half a year later her father remarried. She had to leave for a boarding school in Bugulma, where her singing talent was first discovered. However, at age 14 she had to start working at a cotton factory. At 18 years of age, she applied to the Mikhail Ippolitov-Ivanov College of Music, but she was rejected, in her own words for her "lack of musical preparation". After completing a preparatory course, she was admitted the next year. This is where she met her future husband, Aleksandr Kostyuk, at the dormitory that they shared with students of the Gnessin State Musical College, where Kostyuk also studied at. In her third year, she was invited to perform with the ensemble Rossiyanochka. Then, she followed Kostyuk to the Gnessin. Kostyuk proposed to her and they married in 1983 in San Francisco. Their son, Grigory was born the next year. In 1988, they established Zolotoe Koltso and started performing abroad. They were more well known abroad than in Russia, and they only became known there from 1993, when the local Soyuz record label offered them a contract.
