One of the organisers, Elvis Stanic, who will also perform at the event, told a news conference last week that the idea was for the musicians to play together for four days and compose songs inspired by the Croatian Mediterranean atmosphere.
The musicians will also explore similarities and differences between cultural traditions and musical expressions of Europe, Africa and Latin America.
The "Jazz Ex tempore" music event will include the performances of Cheick-Tidiane Seck, Silvano Mustelier Cabrejas, Arnaud Dalefosse, Vasil Hadzimanov, Giovanni Toffoloni and Elvis Stanic.
The show, organised by the Liburnia Jazz Association and Festival Opatija, will be held under the auspices of the Croatian Culture Ministry.
