The song moves by angry electronic waves that progressively and aggressively beat James Mercer’s anxious voice which inspires fear and urgency.
There is in fact a sense of emergency all along the song which appears to culminate when the powerful vocals come into a series of short ripples and seem to run away above some scared keyboard and agitated percussion.
I am not sure of what sort of danger they are fleeing from but you can listen to the song on Broken Bells myspace page:
