"The Who" was the loudest band, if you had a decibel meter at their concerts, you can measure for yourself. I hope I can see the remaining members perform live sometime. The "30 Years" disc set is a very good collection with some vintage live performances. The book that comes with the disc set contains lot of photos, news. I need to get "Tommy" and I will be all set I think.
