In October 2010 the agreement of collaboration was signed between the composers’ associations of Macedonia (SAKOM), represented by Jana Andreevska, artistic director for international activities, Slovenia (DSS), represented by Dušan Bavdek, artistic director for international activities, and Serbia (UKS), represented by Ivana Trišić, the president. The agreement was not official. It was cordial, friendly and efficient. The first project of the collaboration was the exchange of chamber ensembles performing programs that include pieces by composers coming from the three countries, and at the contemporary music festivals each association organizes in its environment. The agreement immediately gave results. Already in March 2011 the piano duo Sonja Lončar – Andrija Pavlović performed at 34th Days of Macedonian Music, and ensembles from Serbia (Aneta Ilić and Katarina Jovanović, sopranos; Stana Krstajić, flute and Natalija Mladenović, piano) and Macedonia (violin players Mihailo Trandafilovski and Peter Sheppard, and pianist Ana Gaceva) performed in Ljubljana on November 5 and 6. The concert entitled Friends from Macedonia is a continuation of the collaboration.
