Obradović's "Concerto for Piano and Orchestra" (1999) also offers a similar programmatic background. The bold musical means that fringe on atonality, especially in the tempestuous first and third movements, reinforce ideological references from the concerto's subtitle "Pro libertate". In the opening part, marked by tempo and character "Allegro risoluto e con colera", prominent are complex clusters, which, according to the composer represent “a reverberation of tumultuous micro-polyphony.” In context of the 1999 NATO bombing of Serbia during which this work was contrived, noteworthy seems the inspiration for the concerto's slow second movement Obradović found in a melody from Mokranjac's "Octoechos". The melody's modal structure insofar effectuated tonal and modal centricity of this movement and the quasi-improvisatory treatment of the adopted melody-theme. The ultimate revelation of the composer's pursuit of freedom emerges in the final movement, in the theme delivered by trumpets, in which Obradović in Morse code conveys the word "libertas"–freedom.
