Co-worker at work told me about this. Thought I'd pass it along...massive for house fans! Almost seems like a Ultra Miami line-up!

and a bunch of others some of you may recognize (honestly I'm not big into the commercial house or dub scene).

Boonstock has typically been a rock festival but looks like they are heading toward the EDM direction...still some rock bands though.

Tickets sales are starting to really pick-up/sell now. If they promoted this a bit more on the web; major websites (ie youtube, DJ mag, etc) fans from the US and other provinces would attend this especially during Canada Day weekend... guaranteed! Will be interesting to see how it turns out.
