Query: ruined by sound engineering

This is a good interpretation but the CD is ruined by the sound engineering that is over the top. The louds are much too loud and the softs too soft so that you have to constantly adjust the volume to compensate. As is the sound is nothing like a normal concert hall performance. It has been sound engineered to death by over the top engineers who think exaggeration is good. It isn't.
