Miša Aleksić started his career in 1970 in a band called Royali as their bass guitarist and vocalist. In 1970 the band won second place at the contest organized by editors of Radio Belgrade show Veče uz radio.
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). After Tasić left the band SOS continued performing as a trio. 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.
On 29 November 2020, Aleksić died following complications from COVID-19. He performed his last concert with Riblja Čorba on 29 February 2020, at Klubar Kranj in Slovenia.[1]
