Vilko & Slavko Avsenik’s ensemble from Slovenia were the creators of the ‘Oberkrainer’ sound and genre which took off in the alpine parts of central Europe. A typical band in this genre, following Avseniki, has three main parts: the vocal, melodic and rhythm sections. The rhythm section in the band is usually made up of the vital three instruments: accordion, guitar and double bass or electric bass which alternates with baritone.
The sound of Slavko and Vilko Avsenik’s ensemble (Slo: Ansambel bratov Avsenik, Ger: Slavko Avsenik und seine Original Oberkrainer) had many moving parts that contributed to the legendary sound which evolved throughout their career spanning from the 1950s to the 1990s. Technique, band members, advancements in sound engineering, arrangements by Vilko Avsenik and combinations of instruments evolved with each album and each decade. This includes the evolution of each accordion that Slavko Avsenik recorded and performed with.
