I started shoving tissue in my ears 25 years or so ago at concerts. Then about 20 years ago I had forgot some at a Heart concert at Universal Studios. Huge mistake not running to the toilet and grabbing some TP and shoving it in. Huge. Loudest thing I was ever at. I always put tissue in after that but the affect/damage had been done that night. For the last few years I have been using Etymotic ear plugs. They work fine and after about 20-30 mins of the show I basically don't care that they are in.
