Popović was born in Belgrade and lived at Alekse Nenadovica street connecting "Slavija" and "Metropol" hotel, inhabited by people from highest social positions, such as lawyers, politicians, musicians, sportsman, etc., to the lowest, such as prostitutes, drug dealers, thieves, etc.
In his early youth he brought some LP compilations of Opatija festivals and played them while using a wooden cigarette box as a drum and after hearing The Who's album A Quick One, he decided to become a drummer.
After Dag, he formed a hard rock trio Jocker, and then Jesen before joining the band of Slađana Milošević.
The band also included Popović on drums, keyboard player Dragan Mitrić, Bora Atić on saxophone and Dragana Milković on piano and vocals.
In early 1979 Popović's future wife got pregnant and he also had to serve the Yugoslav People's Army which caused the breaking up of the band.
The next release was the album Čokolada featuring bassist Branko Isaković instead of Zdenko Kolar who went to serve the Yugoslav People's Army.
The last release as Idoli was a soundtrack album for Šest dana juna which was written by Divljan while the rest of the band recorded their parts.
