It's pretty common knowledge that parents and/or older people don't "understand" the music of us younger generations. That's always been the case, and I doubt it will ever change. Case in point: today my mom was questioning *ahem* my musical tastes because I was listening to Vidoll's "Remind Story". It's the one with the aria in the middle. Now, Jui is operatically trained and sings the notes beautifully, with the perfect amount of vibrato and he is absolutely on pitch, as he always is. Still, my mom wrote it off as weird automatically because "opera does not belong in a rock song."
This made me think. Usually older generations criticize new music because it is too loud and noisy. They think the singers can't sing, they only scream, etc etc. This was not the case today, however. Jui very obviously can sing. And the song is not particularly loud or hectic. So the problem then was in fact Vidoll's innovation of using opera in an unexpected way. In fact, he was being criticized because he CAN sing, not because he can't. Odd.
I can think of two reasons for this. The first can be traced back to the 50s and 60s, the era most of our parents grew up in. True, this was a era of musical experimentation that may never be rivalled. However, most of the music remained simplistic. The majority of singers really weren't very talented (ie. had small ranges and little vocal training), guitarwork was very limited (most songs included only a few chords and nothing so intricate as we hear today). The lyrics for the most part fell into very broad categories and were predictable, as were the melodies. I can sing along to a 50s song without every hearing it before due to this fact. Now, I am over-generalizing, but I think this paradigm has left most adults unable to understand or appreciate more complex music that is being created today. Instead of seeing innovation for what it is, they see it as noise. That was certainly true during the 70s and 80s when artists like Jimmi Hendrix, Eric Clapton, and metal guitarists were pushing the limits of what could be done with the guitar. Their works were sometimes dismissed as being unmusical.
The second reason is the current popular music scene, which has stagnated to a horrible degree. At one point in history, you could turn on the radio and hear the best artists of the day, the ones that were really pushing the envelope (The Beatles, the Rolling Stones, Queen, etc etc). Now, and this has been true since the mid-80s, people would rather hear "safe" music that doesn't redefine or question anything. You have to search through smaller stations and music shops to find the really innovative artists. This is changing the way music is viewed and affects people, negatively I think.
I guess what I'm trying to say is that the majority of people today are unwilling to try new kinds of music because they have been so conditioned to what I call "safe" music. Anything that strays from the norm is seen as weird. So, I'd like to close my little rant with this fact: The Waltz was once banned for being too provocative and "weird." Look how far we've come.
