Sonica Festival in Ljubljana
Sonica International Festival of Transitory Art is Ljubljana's longest-running festival of exploratory and experimental electronic music and sound art, founded in 2009. Historically held in spring, it merges music with visual and intermedia art through concerts, club nights, exhibitions, and talks, with a strong international focus on artists from the Balkans and Eastern Europe.
Sonica International Festival of Transitory Art started in 2009, and by the time a 2017 listing described it as reaching its ninth edition, it had already established itself as Ljubljana's, and by extension Slovenia's, longest-running festival dedicated to exploratory and experimental electronic music.
