I like to dance! Here's some stuff I've been to in North Seattle. All have live music.
I've been jumping into all kinds of styles, it's a bit ridiculous.
Tip for newcomers: There's a mailing list for everything. Ask around when you go to a jam to get on it :) Play at a respectful volume; you should be able to hear the leader (unless everyone is jamming out on a serious bop). If you're not sure about etiquette, ask! It's helpful to learn a few tunes beforehand, so I listed some below.
