@#15 ... Fun fact (or rumor)..Tangerine Dream used to be one of the LOUDEST bands in their shows. ...
The loudest band I ever experienced in a concert was Heart.
John Cougar was the warm-up act in the New Haven Coliseum ((late 1970's, before he became ~known~).
My friend and I went to attend a Heart show.
Well, Mr Mellancamp, in his opening act, blew the doors off the place.
Heart, (and I did have, and continue to have, great respect for their talent) saw his performance and, I guess, figured they need to top it.
So, they turned up the volume. A lot.
My friend and I were happy that I brought ear plugs for us to reduce the volume, so we could enjoy the rest of the concert.
