Yes let's quote here all the Wacken Epica part review's we can find.
Here is from Metal Storm
Gorm: After spending a few hours away from the main stages throwing down a few beers I returned to see Epica. And I will never regret doing that. For once I was standing fairly well and had a good view of the whole stage. The sound was spot on as well and the band delivered the best they had…and that was really good. Actually everything was pretty much perfect. The tracklist, the interaction with the crowd, the lighting, and pyrotechnics. This was without a doubt the best concert of the festival for me.
