The Age of Adz (pronounced Odds) is Sufjan Stevens’ first full-length collection of original songs since 2005’s conceptual pop opus Illinois. This new album is probably his most unusual, first, for its lack of conceptual underpinnings, and second, for its extensive use of electronics. The album almost entirely eschews the songwriter’s former tools of the trade: namely, acoustic instruments that accompany an expansive narrative scope. While the sounds on this record are distinctly “artificial” (drums machines and analog synthesizers 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, more primary, and more 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). Love, sex, death, disease, illness, anxiety, and suicide make appearances in an aggressive (and sometimes danceable) tapestry of electronic pop, conveyed with the urgency, immediacy, and anxiety of primary colors.
