DnB isn't nearly as big here as it is in Europe. For example: its never played on the radio except maybe a college station. The amount of people at events depends on the region. The SouthWest has a pretty big DnB scene as does the North East. Where I live in Chicago its not nearly as big, but it is starting to get larger. A few years back it was pretty popular, but it died out and is now starting to grow again. House is huge in Chicago and the midwest, and it looks like with Daft Punk coming over here and other bands like Justice that the US may start to get big into house. More and more people get into EDM every day. The West coast has a huge psytrance scene.

I don't think DnB will ever reach UK proportions over here. I lived in London for half a year and was blown out of my mind. I was in heaven over there.
