Oh, it was surprisingly small, like 4 groups of 6-8 people each. I'm actually not into metal too, but metal/hard rock is such a wide definition that everyone finds something to his liking. From electronic bangers to legitimate opera, it's more a live show with a band behind singers. But of course here the noisy bangy screamy stuff wins, this is theatre for true classic rockers. People in Harley Davidson jackets and beer come to watch😁
