Before Michigan, Sufjan Stevens was a footnote within a curiosity. In 2003, the Michigan-raised Brooklyn transplant was best known as part of the entourage surrounding Daniel Smith’s off-kilter Christian rock collective Danielson Famile, a group whose costumed insanity presaged the drama club-meets-cheerleading squad shtick that later defined Sufjan’s live show. He’d already released two albums before 2003, but barely anybody heard them. Even those who did encounter 2000’s A Sun Came and 2001’s Enjoy Your Rabbitprobably were not prepared for the exquisite deluge Sufjan released 10 years ago today. His widescreen love letter to his home state was such a momentous leap forward that a decade later he still hasn’t surpassed it — not with the stark spiritual meditation Seven Swans, not with the brilliant but cartoonishly grandiose Illinois, and not with the striking digital freakout The Age Of Adz. Sufjan has produced a wealth of fascinating, deeply affecting (and sometimes deeply affected) music over the years, but none of it beats the record that literally and figuratively put him on the map.
