Yes, I obviously went to an underground fight show last Sunday. No, I am not done writing the article on it - it takes time to make the words pretty. But in the meantime, here are some videos from the event. In terms of atmosphere, BX Fight Club is one of the best shows I've ever been to, and you can get a glimpse of that here.
Events are every Sunday, so if you're interested... well, the first rule is I'm not supposed to talk about it.
