When I was Younger (howling sound)....a long time ago. I studied music, Orchestra to be exact (cello/bass). I remember sitting in class, my walkman cassette player on, full blast to the sounds of Van Halen, Ratt, Led Zeppelin, and yes AC/DC!
My teachers walking in and telling to turn that "crap" off !
I will never forgot the day that ALL my teachers at one point or another would say... "That Rock and Roll stuff has no place in Classical music!"
