UB40 Were Pretty Loud

Ever been to a show that was so loud it caused your ears to bleed? Regge-rockers UB40 played a show the other day that apparently left many concert-goer's with some ringing ears and "altering heart rhythms" as reported. I do love watching live shows and most I have found are not horrendously loud as claimed by this woman in the article [below.]  Granted, there have been times when I've found the sound to be above my comfort level.  I wasn't there, so I can't say for sure about her experience, but I have two words and a sentence for her.  Ear Plugs... and... it sounds as if she had a pre-existing condition.
