Brit bird in town for Halloween! How to find an American experience to remember?

I’m coming into Houston from 10/29 – 11/2. I’ve never been in the US for Halloween before. We don’t really celebrate it like you do, it’s a lot more muted here, like most things. How can I find the kind of Halloween I’ve seen in the media? I’m youngish, into most music and scenes, love silliness and whimsey, and have never been to any southern states before so would love to feel a bit of that vibe. I understand it’s not quite cowboy country but if I could see just one person in a Stetson who calls me ma’am, I might implode!! I’m a big lover of indie events so if anyone’s got a band playing, or knows a cool bar to soak up the atmosphere, I’d be so grateful. I also have some American foods I’ve not yet tried so would be grateful to find the local specialists: BBQ Crawfish boil Chicken fried steak

Apologies for sounding like a bloody tourist, I am just very excited and as a Brit, we don’t really know what to do with extreme emotion 🙂
