Approximate translation to English by the cellist (BTW the original press release was in High German, not Swiss German):

After the intermission the band "Terrible Noise" played. However, their performance did certainly not conform to their name, since what they played had nothing in common with "terrible noise". They were simply phantastic! :-) Their songs were imaginative, avant-gardistic, and technically well performed. Unfortunately not all of the audience seemed to fully appreciate this fact, since some people's discussions interfered with the music during very low volume parts of the performance. Precisely these interludes were of a great musicality and sometimes were reminiscent of Pink Floyd. Nobody of this band stuck out, instead the band performed as a unit. All instruments, by the way among which were a flute and a cello, had their solo parts. The performance was a success. According to the applause the audience loved the bands and we can only hope that a similar concert will be organised soon again.
