That brickwalling is a very sad development over the past couple of decades. Sad to hear it was used on this CD, although I have seen far, far worse. Brickwalling sucks the life out of the music. That is one reason it is sometimes better to buy vinyl when it is available--the mastering is sometimes better than the digital versions, meaning the bass isn't slammed and the digital brickwalling to make it louder are both tamed down or even absent. (Other times, no...the vinyl is just cut from the poor digital mastering.) It's just the way it is these days...the loudness wars will never go away.
