Last night in the Hall of the First Kragujevac Gymnasium we officially opened the Third Internationale festival of chamber music Convivium Musicum. Numerous audience seemed to be waiting for this festival and concerts that the organizers and performers prepared for them. Ensemble LID, Ljudmila Gros-Petrović – soprano, Igor Lazic – horn and Dejan Subotic – piano based their program on the works of French and Russian school of the late nineteenth and early twentieth century. Impressionist coloratura in the works of Debussy and Massenet, as well as work of Ippolit- Ivanov and Glier that brought the sound of German lid tradition, delighted the audience awarded performers with the long applause and shouts of “bravo!”. This unusual trio greatly balanced the very different colors of piano, horn and the human voice. This was largely contributed to the excellent arrangements Igor Lazic,who adjusted most of the composition to the performing ensemble.
