Kočani Orkestar's debut showcases the intoxicating rhythmic thrust and complex melodies of Balkan music. Combining brass and reed instruments with drums and accordions for a sound that turns any Eastern European party into an all-night rager, tracks like the slow-building "Srpsko Oro" and the jazzily syncopated "Nejatov Cocek" are made for communal dancing. A handful of cuts featuring siren-voiced Violeta Filipova are thrilling, but the tuba-driven throb and wild solos of tunes like "Bulgarska Oro" reveal the full power of Balkan brass.
