Holy heck, these guys are simply amazing. Here's their bandcamp. Their albums are great, but their live performances are just... something else.
I saw them live on Saturday 17th, at the Brooklyn Bowl at the Millenium Dome (O2 something?), and it was absolutely wonderful.
I've been enjoying the live shows posted on YouTube (though a few have now been taken down, sad face). As an aside: I totally understand if someone wants to take down a video of something because they're selling it - but it turns out I can't buy the stream anymore, because they only sold it prior to the event. Hmph.
Anyway, these guys rock, and I could go on for hours about how much I think so.
