Hey, this community college station in Seattle has a weekly ska show that's actually really good. They have a live band in studio every week it looks like and they podcast the shows each time, so you can listen to past shows.
Here's their page:

Also, they had this young band on this week called Juice. I saw them live the other weekend and they were fun and hilarious. You should check for the podcast of this week's show to hear their awesome cover of date rape.
