Though the festival has an international line-up, its main focus has always been set on quality world and rock bands from Slovenia, many of them regularly returning to its stage. The festival is also a part of an informal network of different festivals and artists, and has already enabled quite a few excursions abroad to the musicians involved.
The main part of the programme usually starts early, sometime during the afternoon, and presents around 6 or 7 bands, half of them (if possible) being lesser-known newcomers and ones from abroad. The rest are the well-established bands like StrojMachine, Same babe, Vlado Kreslin in Beltinška banda, Tolovaj Mataj, Terrafolk, Brencl Banda, Orlek, Slon in sadež, Bossa de Novo, Marko Hatlak, Čompe, Fake Orchestra, Katalena and – each year – Kontrabant. The foreign guests include the Filth (USA), Zuf de Žur (IT), Etnoploč (IT), Hetret (HU), Strune (MK), Belfast Food (HR), and Banda Berimbau (IT).
Since 2011, the Festival of Ethno and Rock also has a second day, which is called Jari ERF (Young Ethno-Rock Festival) and which engages with kids, mainly those between 4 and 12 years of age. The stage is reserved for young musicians of about that age, the invited audience is their contemporaries, and a music workshop takes place led by an established folk band. All of this furthers the main ambition of the festival – to facilitate Slovene folk music in its contemporary life and to pass it on to the next generation.
