Denis & Denis was a Croatian and Yugoslav synth-pop group formed in Rijeka in 1982. They were one of the most prominent and most popular acts of the Yugoslav synth-pop scene.
Formed as a duo consisting of keyboardist and vocalist Davor Tolja and vocalist Marina Perazić, Denis & Denis immediately gained attention of the Yugoslav audience with their first recordings broadcast on Yugoslav radio stations. Their debut album, Čuvaj se!, released in 1984, brought them nationwide popularity, Perazić becoming one of the biggest stars and sex symbols of the Yugoslav rock scene. Their second album, Ja sam lažljiva, was recorded during Tolja's military leaves from the Yugoslav army, so for the live performances he was replaced by Edi Kraljić, his former bandmate from the band Linija 32. Ja sam lažljiva brought new hits and increased the group's popularity. After Tolja's return from the army, the group continued working as a trio consisting of Tolja, Perazić and Kraljić. After Perazić left the group in 1986 to start a solo career, Tolja and Kraljić continued working as Denis & Denis, turning towards pop rock sound.
