Last night I was seeing Tegan and Sara w/ Northern State at The Showbox in Seattle. It was a lot of fun. Northern State were touring with Tegan and Sara the last time I saw them, too. They're very fun to see live, and my brother-in-law, who wanted to hate three white girl rappers, was actually nodding along with their music and applauding after each song. He was completely bored during Tegan and Sara, though.
Tegan and Sara did get off to a rocky start. They weren't really hitting their mark, but after a few they started to get better. Sara was sick, but she said she felt better while performing. My sister liked Northern State's performance more, too, and I can understand why. Their music is generally catchier, and in most cases, Tegan and Sara's music is something I'd rather listen to at home, when I'm in the right mood for it. Plus, they were guilty of having it blasted way too loud. I think their live show would benefit from backing off of the volume. I really should have remembered earplugs.
I'm glad they talked more than the time I saw them in Portland. The Portland audience was too unruly, and Tegan and Sara gave up trying to tell their stories. I remember Sara saying in an interview on Amazon.com that they love playing Seattle, maybe the most, and they certainly seemed to be in a better mood than when they were in Portland. Some bands shouldn't try to talk between songs, but I really enjoy the stories they tell.

Northern State's banter was pretty funny, too. I get their newsletter, and they've mentioned on numerous occasions about being huge fans of Grey's Anatomy. You can imagine their excitement both times they got to announce a song of theirs being featured on the show. I don't think I'd be a fan of the show (only saw part of one episode), but it's fun to see others take that much pleasure in something.
It was enjoyable. I think I'm good now, having seen them both twice. I mainly went to this concert to get my sister to go, since she also likes both bands, and she doesn't end up going to concerts unless I make her. Anyway, fun stuff!
The only thing is that I should have bought more of the Tegan and Sara scarves. I bought one for my sister and one for Cari, but I could have made some money by selling extras on eBay.
