Festival which suits my line-up preference to the max. The very best of extreme metal and closely related genres is showcased each year. This year was my 10th edition. Line-up remains strong but services and the quality of venue as such are improving constantly year after year. The setting itself (a massive fortress from 18th century) makes it absolutely unique.

Best festival ever, even when they have some problems - trying hard to solve them. Great food, lot of merch, wonderful people from all over the world. Must see and HEAR! Hope to visit again in 2023.

Best Festival with amazing crews, staffs and friendly metalheads from everywhere around the world. Great Bands performing with no restrictions, everything goes! Reasonable price for wide variety food and drinks. 2023 was my 4th Time and i wish they will keep the prices stay low! Stay Heavy For The Music!

Long, long time one of the best metal event in Europe.

The best festival for Brutal metal, nice bands, nice food... They has four stages with many metal styles playing at same time. The food options are great, vegan, Mexican, Indian etc. The merch is great with many tshirts options. I'm going every year.

Excellent festival. Not too big, perfectly organized. Recommend

I have been to this metal festival twice now and have next to nothing to compare it to apart from the horror stories from other festivals. People here are super friendly and focused on music, the location is awesome, line-up is always stacked and prices are very reasonable. Can't recommend this festival enough if you're into extreme metal(as well as other niches of music).

Possibly the best festival of its kind in Europe. Been running for 20+ years and you can tell! Terrific organisation, smart layout to avoid overcrowding and insane number of food and entertainment options! And of course the music! Lineup neatly organized to minimize scheduling conflicts. Sound quality is fantastic for the biggest stages and great for the smaller stages. Only recommendations: more indoor seating and cheaper price for water. And better layout for the smaller stages.
