Interesting Subculture

I think an interesting subculture that we have not talked about is the rave subculture.  I think this would be interesting because I think it has become more relevant in modern times due to the rise in popularity of techno music.  The music and drug use is pretty much the only thing about the rave subculture that I know about and I was just wondering if there was more to it than that.  Are there specific ideas and ideologies of the rave culture? I think it would be informative to look into because of it becoming more mainstream.
