I'm 36 and still get down in the Sahara tent. I went Sunday with some friends who were older than me and they were going crazy for Justice. I think a lot of the feeling for music goes back to what you were listening to as a child and teen. Myself, I grew up on shit like Rick James, RFTW and anything Prince related...so when electroclash came along in the mid/late 90's I was hooked. Same thing with disco, I bet you get some 30, 40, 50 year old's to listen to In Flagranti, LCD or David Carretta and you're gonna see them dancing too. I love seeing the young DJ's and bands putting a different spin on the old stuff. You can have young and old enjoying music together.
