These 18 compositions for string quartet, written by the long-standing bass player of the rock band Opus, Peter N Gruber, are intended to abduct us into a distant garden. They are enthralling pieces with fascinating effects, cultivated from improvised music for the double bass, often with literary references, and they immerse the listener in a realm of sound that can quench the thirst for tranquillity and deceleration in these hectic and boisterous times.

The Frozen Fritz 4 (Igmar Jenner, Andreas Semlitsch - violin; Simon Schellnegger - viola; Sophie Abraham - cello) interpret entertaining works with titles such as Apple John, Schäfchen zählen ('Counting Sheep'), Galgenhumoreske ('Gallows' Humoresque') or Mövenpicknick, whose conception transforms the profound experiences from the composer's 40 years as a musician, inviting the audience to participate in creating music through active listening.
