"Serbians' passion for brass music dates from the nineteenth century, when the first military bands were formed. With Serbia still under the rule of the Ottoman Empire, trumpet music became a form of national expression and celebration, mixing traditional Serbian music with eastern-influenced Turkish and Gypsy rhythms. Many of the best bands and performers, including Guca legend Boban Markovic, come from Serbia's Roma community. Guca organizer Adam Tadic told CNN that the sound of the trumpet had once been a call to arms for Serbs to come to the defense of their nation. "The trumpet isn't a traditional Serbian instrument but, through the history and the struggle for survival of this nation, it came into our hearts. Now it's a part of Serbian identity forever," he said."
