The Age of Adz (pronounced Odds) is Sufjan Stevens' first full-length collection of original songs since 2005's conceptual pop opus Illinois. While the sounds on this record are distinctly "artificial" (drums machines and analog synths reign supreme), the proclamations of the songs are unabashedly visceral, sung loudly, with a backdrop of insistent orchestration. The result is an album that is perhaps more vibrant, primary and explicit than anything Sufjan has done before, incorporating themes that are neither historical nor civic, but rather personal and primal (if even a little juvenile).
