Chris Walla of Death Cab For Cutie and J.Robbins of Jawbox and Burning Airlines were invited to NPR to participate in the Project Song Challenge. The two musicians met for the first time earlier this month and were tasked with writing and recording a new track.

Bob Boilen of NPR explained:

I supplied some inspiration for their song: photo collages created by artist Tom Chambers. They chose a photograph of a house in a canyon filled with water, tilted and flooded. Not far from the house is a dog on a boat, floating either toward or away from the house. I also supplied a series of words. They selected the word "cerebral" and promised when they wrote the song not to be too cerebral about it. You can hear the music and watch a video documenting the creative process as it unfolds.
