Volkshaus, Offbeat Jazzfestival, Basel, Switzerland. A sound support with provocative combinations, a modern music laboratory, a vehicle of inspiration whose importance has been proven by many high-profile collaborations. Music lovers who appreciate jazz for its ability to provoke and continuously question the status quo certainly do not expect that such a standard set in its configuration finds itself completely detached from tradition. But sometimes, the more the DNA of a set is anchored in tradition, the higher the margin to give way to novelty. Innovation is at the heart of the approach of VEIN, a bold Swiss ensemble composed of brothers Michael and Florian Arbenz, and bassist Thomas Lähns, for whom the term "piano trio" has long been too restrictive.
