This is off topic but the last ten or so years, the volume level at shows has gone over the top. I did indoor and outdoor shows in the 80s and 90s without plugs and worst case was a little ringing the next day. I mostly did outdoor concerts in the 2000's so I don't know what indoor shows were like but in 2013 I started taking my daughter to shows and holly shit balls it was loud. The last show that I went to I had to step outside to get a break even though I was wearing -32db plugs.
