Since 1995 the Summer Music Festival at Podsreda Castle has regularly taken place at Kozjanski park. During summer months, musical performances by masters and their students resonate among the castle walls and the music programme and music seminars contribute significantly to keeping the castle alive with activity. The seminars, which feature internationally renowned musicians, are the only events of this kind in the Kozjanski region. Work at the seminars includes technically focused individual music lessons as well as ensemble music-making. The artistic director of the festival is professor Andrej Zupan.
