The above clip is from what used to be called "Sensation White", which started in Holland in 2000, and now it is a worldwide event. At the beginning there was only Sensation, then it was decided they were going to split the party in two: Sensation White and Sensation Black.
Sensation Black focuses more on darker music, like Hard style and Hardcore, whereas Sensation White focuses more on House and Trance.
Finally, it was decided that "Sensation White" would become "Sensation", and "Sensation Black" would be just "Black".

Nowhere in the official website (www.sensation.com) you will find any Sensation event happening in North America, nevertheless Quebec City and Montreal just had their own Sensation parties - are they affiliated to the same event?
