What an unwieldy title! "True In No Possible World" is the motto of the debut album of the saxophonist and composer Benedict Koch, and everyone wonders what he really means. The term originates from modal logic, a branch of the logic that deals with the consequences of the modal terms "possible" and "necessary." As a result, you can not only derive secure statements such as "it is raining" or "All circles are round" from modal logic, but also such theses that question them in principle: "It is maybe raining" or "All circles are necessarily round." Confusing? Possibly. But Benedict Koch is less interested in a deeper meaning, with which his music could be analyzed and lifted to an intellectually higher level. "I chose this sentence above all because it fits phonetically to my music," the 30-year-old gave the answer to the riddle in an amazingly simple way. Koch has here created an album full of facets, mild shimmering colors and finely regulated feelings of melancholy all the way to cautious joy with his new quintet.
