[4] With schoolmate Gagi Mihajlović, Mladenović formed a band called Limunovo Drvo (Lemon Tree) that dabbled in melodic hard rock.

The group changed lineups frequently, displaying a limited creative potential until the arrival of bassist Dušan "Koja" Kojić and drummer Ivan "Vd" Vdović.

Šarlo Akrobata released only one album, Bistriji ili tuplji čovek biva kad... in July 1981 and broke up soon afterward due to creative differences between Milan and Koja.

In late 1981 Milan and his former bandmate from Limunovo drvo Gagi Mihajlović (guitar) hooked up again to form Katarina II.

Their next album S' vetrom uz lice launched them to the very top of the Yugoslav music scene, where they stayed for a long time, releasing a series of successful records.

[5] In the spring of 1994, Mladenović recorded and released an album called Angel's Breath in Brazil together with his old friend Suba (Mitar Subotić).
