Many bands have claimed to be the loudest, some doing it while giving in demands from Grandpas to turn it down (1)
However, no band has ever came close to reaching the sheer awesome loudness of the warriors know as Manowar, with the except of Motorhead (2) (possibly)
We the undersigned believe that Manowar should be given a medal and possibly very large swords for being the loudest band on Earth, reaching an amazing SPL of 139 dBs.
Footnotes:
(1) in 2009 KISS reached 136 but had to turn it down because fans complained about the show
(2) Rumours abound that Motorhead reached a level of 130 dB in Cleveland, OH and damaged a part of the Variety theatre.
