In 1989 Kovač and her younger sister Kristina formed a duo named K2, and signed a five-year recording contract with Dave Margereson and Kenny Thompson from Mismanagement, a record label based in London. The same year they supported Labi Sifre at his tour in England. The sister supported Bebi Dol in her song "Brazil" at the Eurovision Song Contest 1991. In 1993 K2 supported Errol Brown from Hot Chocolate on a tour. After the tour, they continued working with Brown's band New Underground, a Manchester based production team, consisting of Robert Maddix and Jonathon Beckford. Working on that project, the sisters discovered soul and funk music, and quickly absorbed the sounds of her Manchester friends’ record collection, which was ripe with old-school soul music, such as Aretha Franklin, Sly Stone, Parliament and Curtis Mayfield. At the same time, Kovač studied classical music at the Belgrade University.
