Former experienced lead singer here... (of no band you've ever heard of). I worked multiple shows, 2 to 4 sets of 45 minutes, just about every weekend for about eight years.

I'm sorry but this is bullshit. If you heard probably 99% of the pop stars these days sing live "unplugged" with no reverb or accompaniment I doubt it would be much better. Beyonce can't sing half as well. Mariah has some def vocal problems, wear and tear from all the riffing and over singing, but this is unfair…
