Saw you guys last in 2012 at Bell Center, and the sound was awful on ground level on Rudy and Pawel's side of the stage. Klaus, your microphone, which you changed did not make a difference. My sister was sitting in stands and she could hear perfectly, but ground level was just horrible. Please triple check your sound system before going on ?, I want to enjoy a good concert August 27th at the Bell Center, ground level on Matthias side. ?
