@star I'd be interested in going, if you would be open to that :3 (The friends I usually attend concerts with aren't really into that kind of music and I wouldn't want to go alone since that usually makes me more anxious than I can enjoy it)
I would recommend to look for a smaller concert in Dresden first, even if its not exactly your style of music, to see if you like concerts as a concept.
There are often some in Ostpool, Chemiefabrik, Alter Schlachthof...
Also dont go alone, if you can avoid it, at least for me, a Concert alone can be a bad experience, even if I like the music.
