When the term dub-step was first coined the genre and the scene as was much different than it is today. At it's roots the genre shared more with breakcore than dance music having consisted of deep bass lines layered over a half-step break beat with minimal ambient elements thrown in to give it a dark organic sounding characteristic. What people call dub-step today is more or less a fusion of the original sound incorporating elements of other genres such as the wobbly and modulated synths heard in fidget house, syncopated leads as heard in dutch house as well as adopting a more 4x4 template that is more synonymous with general house music. From a technical production standpoint the musical style that which most people identify as dub-step is more or less a hybrid form of what the genre was originally recognized as by it's pioneers.
While dub-step wasn't created with the intent to create a counter response to existing scenes and genres, it has been perceived as such through the over promotion of the genre by radio hosts , club promoters and DJ's who see themselves as taste makers and trend setters. For when it comes to the general public, the majority only care about what will make them seem cool or ahead of the curve, regardless of the artistic merit or intentions of the creators. It is the audience that which determines how commercialized a genre become based on the amount of exposure they are subjected to whether it be the mainstream media, the internet, a movie, a local club or even a television commercial. In short it becomes embedded as an aspect of everyday culture people begin to identify with.
In short, no. It was not created as a counter response to other genres or scene however, it has been touted and branded indefinitely as "the next big thing" by those in the industry looking to capitalize and cash in on the profitability of something they can sell to the masses...Not too far off from the strategy of the Obama campaigned used to desperately propel a mere product into mainstream gold.
Underground genres of electronic music is just the creation of music outside of the norm of standard instruments such as guitars drums and pianos. With that said, most of the instruments are just variations of the instruments that you came around in high school band classes. The beauty of music is that its the persons take on what they would like it to sound.
Dubstep is a commercial counter-cultural response to underground genres of electronic music such as psytrance. This is because every form of modern music gets both imitated and respun so another adapter can claim he/she has created something new. These two genres can live side-by-side and be enjoyed even by the same people.
No, dubstep is not a commercial counter-cultural response to underground genres of electronic music such as psytrance, because the two developed with minimal affiliation and influence on each other. The creators of dubstep created it and sell it because it sells and they can make a profit. They would market their music with or without psytrance.
Dubstep is not a cultural counter response at all. Dubstep is a creative, specific type of music created on the underground and it is now exploding. Maybe the creators felt a need for something fresh and now, as is the case for most musicians, but it was not a counter response at all.
I do not believe dubstep is a commercial counter-cultural response to underground genres of electronic music such as psytrance. I believe people who attempt to throw music into these small genre niches are missing the point of music. Music doesn't have to fit into a specific genre to be something and rarely are trends part of some commercial response or part of broad culture. Music tends to influence, that is all.
