One of my favorite bands (Karma and the Killjoys) announced they were going to tour and I was super excited, but they're only a support band. It's at a bar/pub. I've never been to a concert in that setting and I'd really like to go. Is it rude or inappropriate if I leave after the band I like plays? I feel like because it's in a low-key setting, it won't be super frowned on, but I just want to confirm before making a fool of myself
