Death Cab For Cutie releases 'Narrow Stairs' today. I recommend listening to it first but if you want to jump the gun and go buy it immediately Best Buy is probably already open.
Here are a few of my favorites from the past.
'I Will Follow You Into The Dark'
The Sound of Settling
I also highly recommend 'The Death of an Interior Decorator' off Transatlanticism, I just couldn't find one worthy on You Tube.
