It’s possible you will feel weird about being there and not enjoy it. I was to two concerts of one of my favorite bands and I just didn’t really get it and enjoy it that much, because it was in a big crowd. The “live” thing just didn’t do it for me, so my conclusion is that I just prefer music by myself.

But the mood at the event itself shouldn’t keep you out, you like what you like and if it’s a cool community, they will not gatekeep it.

Showing up alone would be a bit weird. With your wife, nobody should give you a second look.
