Quick Serbian Language lesson:His music is more traditional than the more modern "crossover" artists using Balkan Brass such as Beirut, Shantel and Balkan Beat Box. The music is Serbian / Former Yugoslavian (read: Macedonian, Montenegro, Albanian, Croatian and Bosnian influences). In some circles, he is considered the "King of Gypsy brass bands"and definitely is a great introduction to Balkan Music. He made a name for himself at the Guca (Gucha, remember the "C" is "ch") Golden Trumpet Music Festival by winning the Golden Trumpet in 2001.
Boban Markovic is pronounced Boban Markovich. The "Ć" is actually a "Ch". This usage of "C" holds true for most Slavic languages.
While Boban Markovich is Roma and plays Balkan Brass music, its difficult to classify what is "Roma" music and what is a national music (Serbian). So just keep in mind that Boban is from Serbia and draws a lot of influences from Serbian culture while also injected Roma style and culture as well.
I just recently saw this album in the Virgin Megastore in Times Square NYC last week:
TRACK #3: SAT
TRACK #4: MUNDO COCEK (excellent, please play)
Also, there is a live recording floating around of Boban Markovich that I've seen recently in record stores:
