An awesome band from Serbia which plays Irish music. Their frontman is called Aca Celtic (Aca is pronounced "Azza", like "pizza" with an A instead of PI) and he rocks. Most of their songs are in English, and they make their own songs (like "Far Away") as well as playing old Irish ones (like "Rocky Road to Dublin").
Aca Celtic was once bullied by one of his teachers in high school and then came back with his crew and dumped the bastard in a garbage container.
Orthodox Celts usually make a New Year concert every year in Serbia.
