Another thought (am I allowed to have two, I'm going to bed next) I look at the website! If I feel happy there and get a sense of what the people are like, a flavour of the amtosphere of the evening, I'm more likely to go and see them, even if the music is something a bit unfamiliar.
Seeing as you admitted your motives!
And speaking as an "enthusiastic follower" who tries to make the website reflect the personality of the performer.
