"The turnout has been exceptional, we've had more than 13,000 visitors so far, so that we expect at least 15,000 by the exhibition's closure at the weekend," Moderna galerija director Zdenka Badovinac has said.

Running since 11 May, the "NSK: From Kapital to Capital" show has drawn a diverse crowd, from NSK buffs to families, students, pensioners to foreign visitors.

The latter group has been prevailing since early July, accounting for 75% of all visitors, Badovinac, who will host the final guided tour of the exhibition on Sunday evening, has told the STA.

The turnout was also great at public tours guided by NSK members and experts, and the accompanying international conference in June had been fully booked way in advance, drawing audiences also via a live stream.

The most comprehensive exhibition of the controversial collective yet has attracted many foreign experts and curators, including representatives of the New York MOMA, the Guggenheim Museum and the Tate.

Badovinac, one of the curators of the show herself, says that even the aficionados learnt much new about the NSK through newly discovered material and fresh, stereotype-defying interpretations.

The NSK phenomenon is discussed in even more detail in an extensive publication that is already in print and will be distributed by the world-renown publisher MIT press.

The exhibition will also be hosted by the Van Abbemuseum in Eindhoven, Netherlands, from April 2016, before travelling on to Moscow in September to be displayed at the Garage Museum of Contemporary Art until January 2017, with further guest appearances still discussed.

NSK, or New Slovenian Art as the name translates into English, was founded by multi-media music band Laibach, visual art group Irwin and the Scipion Nasice Sisters Theatre.

It then expanded to several more outfits, including graphic design studio New Collectivism and the Department of Pure and Applied Philosophy.

Its groups had a major impact on the Yugoslav art scene in the 1980s focusing on the relationship between ideology and art in the West and East.
