PRIM was formed in 2015 by three musicians associated with Vienna's vibrating music scene and they have since then managed to impress critics and crowds alike with their progressive sound and technical virtuosity. The cultural scene of their home base Vienna - the world's capital of classical music - serves as an interesting background for their rather experimental but nonetheless accessible style. Their intriguing compositions and innovative use of the standard piano trio line-up differentiates them from standard jazz trios. Despite their diverse musical inspirations and individual manner of playing, they complement each other perfectly. Christoph Karas's polyrhythmic illusions harmonize with Felix Biller's lyricism and Martin Melzer’s underlying bass melodies.

This collaboration results in imaginative, visually evocative music. The debut album, More & Less Diminished, released in 2016 in a different line-up (Biller, Konuray Mutluer, Ralph Dammerer) was described as showing "how jazz in Austria can and should sound" ( One year later, the EP 40 Days (Biller, Mutluer, Sherif Abdalla) proved that the band is constantly experimenting with sounds and schemes in order to reach an exceptional narrative quality. Enthusiastically received by the public in many concert venues around Europe (also sharing the stage with the likes of Woody Black 4 or Sketchbook Quartett i.a.) and featured in radio shows like the Ö1 Jazznight among others, they show that Vienna and jazz have a lot to offer.
