Cave times were repeatedly triggered in prehistory by climatic catastrophes that occurred unexpectedly and forced a greatly reduced population of Homo sapiens into retreat areas. Caving expertise, as it is called today, ensured that mankind was able to survive despite drastic changes in lifestyle and longer periods of cave use. On the basis of his scientific research, university professor and communication researcher Jürgen Grimm developed 52 exercises to increase this cave competence, which can be experienced here in the form of a total work of art.

The composer Friedrich Gernsheim, who was highly respected during his lifetime, is largely unknown today. Yet, especially in his choral compositions, he broke away from traditional ideas of form at an early stage and was thus ahead of many of his contemporaries. With this recording, Tristan Meister and Vox Quadrata have set themselves the goal of bringing the forgotten choral works of the Jewish composer back into the public consciousness.
