Ad Gloriam Brass is an ensemble of six brass winds, members of the Croatian National Theatre Opera Orchestra, Croatian Radio Television Symphony Orchestra, and the Zagreb Philharmonics. The ensemble was formed in 1993. They perform a broad repertoire ranging from European and Croatian renaissance and baroque masters to contemporary Croatian composers, some of which have dedicated their works to the ensemble. Their appearances in a number of festivals in Croatia (Osor Music Evenings, Varaždin Baroque Evenings, Music Evenings in St. Donat's), concerts held abroad, collaborations with artists such as Mario Penzar, Igor Lešnik, the Zagreb Saxophone Quartet and recordings for Croatian Radio Television's broadcasts make them one of the most prominent chamber ensembles on the very top of Croatian scene.
