Yeah, it needs some definite work before it's HARD enough. But I'm going to try and not take the typical WUB UP EVERYTHING/MAKE THE METER RED approach, and take an original approach at this.
Sure, I'll have to add some elements to make it HARDER, but I'm going to try something that doesn't follow the current Balloon Party trend (dubstep and hardcore to name two VERY popular BP genres)
WEE WOO WEE WOO WEE WOO WEE WOO Hipster Alert, Hipster Alert.
For starters, making everything clip would not make it hard...just noisy and hard to listen to. One of the largest elements of intense music is the creation of tension and anticipation through either dissonance or repetition, the use of filtering and so on.
The reason Dubstep and DnB tend to be popular when it comes to hard electronic, is because they both tend to be in minor keys, where dissonance is easy to create, and they use thick saturated sounds as opposed to tradition trance, house music, or other, earlier forms of electronic.
You can take the "Original" approach, but most likely will end up with something very dissonant, something containing thick sounds, and constant changing of sounds. AKA some form music you can relate to Dubstep/dnb/electrohouse/complextro. Or maybe you'll end up with something more epic like Makkons "Dregs" which circled around the, V of the harmonic minor it was in, creating dissonance, and the yearning to hear DO again! There is a way things work ya know!
Now I'm off to work on a second track!
