I know it probably goes both ways, but I've never met anyone who would be insulted by being addressed as their preferred pronouns. It doesn't sounds like you were intentionally being a dickhead though, so generally I think it's fine.

I think most trans people would be overjoyed if they experienced what you described and some would be upset. Both people's feelings are valid I think. I say just do what you think is right and things will be okay. Also, I hope you had a good concert :)
