You know, I wonder if this has anything to do with the “sound wars” of the 90s… like, albums are recorded at a higher level now. Put in an early 90s CD and one from the past 15 or so years, and you can see the difference. I wonder if there was a similar thing with live shows, too, around the same time? We can’t really go back to check the noise levels of concerts prior to the mid-90s, as time travel isn’t a thing.
