Dejan's trademark is his fondness for classical music, jazz, and intricate rhythmic patterns typical of the Balkans, as well as his emotional expression.

His solo performances are warm and intimate.
 

Dejan has performed in more than twenty–five countries around the globe (among them the USA, China, Japan, Britain, France, Russia, and Germany) both independently and as the leader of the acclaimed jazz-rock band EYOT.

Aside from 5 released albums of EYOT, where he is signed as the sole composer, Dejan released five solo piano projects for the US market, under 90&9 Records and Magnatune labels, and one more for Serbian label Metropolis.
