It seems Arcade Fire was thinking in terms of sides when they sequenced The Suburbs.
Recall that the opening (and title) track kicks off with the lines “In the suburbs I, I learned to drive, and you told me we’d never survive. Grab your mother’s keys we’re leavin’.”
Now midway through this song, titled ‘Suburban War,’ we have “In the suburbs I, I learned to drive, and you told me we would never survive. So grab your mother’s keys we leave tonight.” We’ve looped back around to the starting point.
