I've been an ATB fan for as long as I've been listening to edm, and I can say that this past Zoo was an awful performance. I would still want him back so he could redeem himself, though.... and with three days, now, I'd expect he'd be there.
As far as the festival goes, I think the price is really good right now. I'm not sure how I feel about the three day thing, but it makes sense from Made's perspective. Both years have been a very good time, but I said in 2009 that the space wasn't big enough for a festival that was sure to grow. And, as expected, it certainly did grow this year. I think Made is actually hoping to thin it out some, while still selling as many, if not more, tickets than this year. I also think that Friday will probably start later, like 4 o'clock.
I have no doubt that the lineup will be top notch in 2011. At the very least it will be comparable to this year and, imo, if you couldn't find something that suited your tastes, then it may be time to evaluate your interest in dance music. Of course there will still be bitching and complaining, which comes with the territory for an event such as this. The dust thing, however, was somewhat of an anomoly this year. It was incredibly dry in the week leading up to Zoo, which created the dust bowl that everyone has complained more than enough about. I don't forsee this happening next year, but if it does, people should be prepared, including Made.
