I'm a old Metalhead since the 69, but unfortunately Wacken is a bit far for me and I always had to limit myself to local concerts and festivals, or, well, because of COVID what is on YT. The positive is that you can discover new bands that even take Metal to a new level.
Of the current bands, my favorites are Vintersea, Be'lakor and Harakiri for the Sky, !!the latter with brutal videos, but painfully true.
