Belzebong - Soooo heavy
Mars Red Sky
Mother Engine - Absolutely stunning
Dÿse - No offense, but this was absolute crap
Ufomammut - OHMYFUCKINGMAMMOTH!
Nice festival, although the weather was a huge pile of shit. Very relaxed, not too many assholes, a beautiful location and drinks/food were quite affordable. And it's even CLEAN, believe it or not. (Aside from the sludge caused by the heavy rain on thursday and friday, of course).
