Chockshut is the evidence that the Koch-Schütz-Studer trio have expanded their lineup, and consequently, their ability to wreak havoc on musical structures everywhere. Adding a guitarist like Stephan Wittwer, for whom heavy metal and free jazz are synonymous terms, or trombonist Andreas Marti, with his penchant for lower-register sheets of sound, or a pianist such as Jacques Demierre, who writes music and plays in the theater, creates a sextet of uncommon possibility. True to form, the ten selections on Chockshut are full of sharp cuts and quick maneuvers to break the music out of any recognizable compositional form.
