Brilliant Dadashova was born into a family of six children. Her mother Gizkhanim Dadashova was a famous accordion player who died in a car accident in 1964. Brilliant Dadashova's older sisters also pursued careers in music. Dadashova first appeared on stage in 1985, when she participated in the annual International Youth Festival in Moscow. Two years later, she won the prestigious All-Union Pop Singers Contest, a singing competition among representatives of the republics of the Soviet Union. In 1990, she graduated from the Azerbaijan National Culture and Arts Institute and became one of Azerbaijan's most successful female singers. She is one of the few pop singers in Azerbaijan, who has given numerous concerts outside of her home country.
