Katarina Popović Kale is a lawyer by profession, a radio host by occupation, a singer-songwriter, and a singing teacher in her free time. Her voice is heard in the afternoons on Rock Radio, where she feels she has found her place discussing various music and other important topics, drawing from her decades-long experience and passionate love for the Belgrade and Serbian rock scene. She approaches these discussions from the perspective of a musician, then a journalist, occasionally an organiser, and sometimes a promoter.
