I actually like Dubstep, even thought I love classical music, rock and oldies like Louis Armstrong, Janis Joplin (my avatar) and so on.
What I look for in music is evasion, loosing my doubts and troubles into something more powerful.
Since I got to Tomorrowland (Belgium), an electro festival, I understand how this kind of music joins the other ones I like: one more reason to agree with thousands of other people about something you like, one way to get away from the world with sounds.
I think that dubstep is like any other kind of music. Your daughter (with great tastes 😉 ) didn't see what's best about it. I saw Skrillex, Swedish House Mafia, Fatboy Slim and so on, and it was magnificient. But, on other stages, there was stupid music like, as she said, beats with no one dancing or even moving.
I tried to create music with Cubase, Fruit loops and so on, and it was truly hard. I'm absolutely sure that people who worked on that one spent a lot of hours behind their screen trying to make something powerful. On that side, it actually looks like other kinds of music.
I play guitar for 12 years now, and I'm sometimes really disapointed about "actual" music, with only four chords, G, Am, F and C, too easy to play, and so on. Even tough it's beautiful, i barely find it "musical" because I can't find how this could even been hard for them to create. Nothing original, nothing beyond what's been already heard. And dubstep is actually original and hard to create.
If you look at it that way, dubstep and electronic music are "actual' music. If you listen to this to "fly" (i don't know how to express that in english), it works and it's really, really powerful, if you find the good one that speaks to you. It's just a hard thing to find...
Please correct my mistakes, I'm sure there is plenty of them, I promise I did my best to avoid them.
