In tribute to the band since they just broke up [read the story below if you haven't already], here is one of the best tracks off the band's only full length album:
The Killingtons - All My Friends Are Vampires
This has a killer guitar line, and J.K.'s vocals have rarely sounded better. If you wanted to define "emo rock," this would be it, as far as I'm concerned. Check out the band's website if you want more info on the now-defunct group.
UPDATE: Okay, I got a full MP3 up. Check it out, it rules.
UPDATE 2: Had to take down the MP3 temporarily; bandwidth issues prevail - Aubin
UPDATE 3: Man, you're probably sick of these now. Anyways, a clip of the song is now up, hopefully sometime soon I can get the whole song up. - Scott
