Miša Aleksić started his career in 1970 in a band called Royali as their bass guitarist and vocalist.

Influenced by the music of Grand Funk Railroad, Deep Purple and Led Zeppelin, after returning to Yugoslavia, Aleksić formed SOS with Dragan Štulović (guitar), Dragan Tasić (guitar) and Stevan Stevanović (drums).

In 1977 Štulović and Stevanović left the band and were replaced by Rajko Kojić and Vicko Milatović.

In 1978 Aleksić, Kojić and Milatović formed Riblja Čorba with a former Rani Mraz member Bora Đorđević.

During his career Aleksić wrote songs for Zdravko Čolić, Biljana Petrović, Jazzy Bell, Milorad Mandić and Run Go.
