In 2014, the festival was prolonged to four days with the option of a week-long camping experience besides the river. The river delineates the Slovenian and Croatian territories, hence the name of the festival that alludes to the so-called Schengen border.
At first, Schengenfest was a rock festival with a slight pop bent, and it hosted musicians like Magnifico, Siddharta, Big Foot Mama, Dan D and also some bands of a more local character. Yet, very soon it added another stage with electronic music and in the years that followed, the stage of Schengenfest has hosted internationally established bands such as Kaiser Chiefs, Skunk Anansie, Guano Apes, HIM, Leningrad Cowboys, Parov Stelar, Gentleman & The Evolution, Dubioza kolektiv, Asian Dub Foundation, Morcheeba, David Morales, Pendulum, etc.
The aforementioned Siddharta and Big Foot Mama have become – along with some others – almost regulars of the festival, which has now hosted a very diverse bunch of Slovenian musicians like Niet, Muff, Zebra Dots, Leeloojamais, Noctiferia, Elvis Jackson, Vlado Kreslin, Zmelkoow, Klemen Klemen, and others. In 2014, the festival cooperated with Kino Šiška Centre for Urban Culture, who took over the main stage on the first evening and brought the South African hip hop act Die Antwoord, along with Kiril Djaikovski, High5, Laibach, and Moveknowledgement.
