The Oberkrainer aus Begunje folk-pop ensemble (Slovenian: Veseli Begunjčani) was started in 2007. Before joining the ensemble, all musicians were members of different folk-pop groups and have extensive experience of playing professionally both at home and abroad. They all hail from the village of Begunje na Gorenjskem or its environs.

Members of the Oberkrainer aus Begunje swear by the authentic folk pop ‘quintet’ music, i.e. music pioneered by the Avsenik Ensemble.
