You don't know anything until you're in the room. You can watch all the Hate5six videos you want, but to truly experience a band that's anywhere near the hardcore spectrum, you need to be there, breathing the same air, braving the same stagedivers. Sometimes, you can get a pretty good idea of how things will go. Certain bands write music in ways specifically tailored to get certain reactions from the crowd, and if you've been to a few shows, then you understand the rituals involved. Even there, though, a hardcore show thrives on a certain level of unpredictable, combustible chaos. And when a band's whole style is built on chaos, then you can't go in there with expectations.
