I blues dance, and I've been to the Friday Night Blues event from that first video! I know a few blues dancers up with you in Portland, too. Sadly, there's not much scene for it where I'm living currently; only a few of us here do it, and we have to travel to really get a good social dance experience outside of messing around.
I came into it from a slightly different angle from most people, since I'm a westie dancer, not a lindy dancer. It's fantastic though, subtle to watch, but dancing blues feels... really good.
If anyone here is in the Bay Area, go check out Friday Night Blues in San Francisco! It's a great time, and comes with lessons.
