In conjunction with Mich and Observer...
As far as electronic genres go, there hasn't been very much fluctuation compared to say the big genres like Rock and Rap and so forth. I personally enjoy almost all of the electronic genres for listening, but can only effectively produce and DJ in a few. The branching of that for me pretty much goes: (Genre) production > (Genre) distribution > (Genre) DJ'ing. That said, the collateral of my movement through that system generates the proper "feeling" of anything I write, play, or mix. So then whatever I write, then becomes whatever I mix. In turn the audience is then directly in effect of me and my music, as is the music and me are on them. It looks something like this;
Audience - Provides negative or positive response to what is played. > Is effected by what is played.
Music - Sanctioned and controlled by DJ. > Is the median for negative or positive response.
DJ - Provides music and median for audience to abide. > Responds to negative or positive response.
As you can see all parts of the equation are connected. This means that if the genre that is not wanted, it will have a negative response to the music, but not because the music is bad or of poor quality. But enough about me, on to business...
The most potent genres currently (from 2005 to the Present) I think include: Hard Style or Hard Trance, Dubstep, Professional Style Dance, Tech or Minimal or Electro House, Traditional House, other types of Trance, Amateur Style Dance and Techno, Detroit Style(s), Classic Techno. In order of potency and is DEPENDING ON AGE GROUP OF LISTENING AUDIENCE.
While I won't talk about how each of these has changed in there own way, I will discuss what the crowd is responding to.
Through studying groups of people at clubs, private parties, and other events I have found that the overall "request" of the current party-going and listening audience is looking for the following:
Intricate rhythms at a speed similar to Rap/Hip-Hop
Contrast between Phrases and Tracks (while still sounding good)
Lyrics and vocal effects (such as Jump Notes or Minimal/Techy FX)
Good Phrasing from Hard to Soft for breaks and rests
Simple, easy to understand overall ideas and song angles
...and a lot more from there.
Hehe... instant gratification... ;)
