People have been saying that C+L is his saddest, most personal release. But have they heard Seven Swans? Seven Swans has Sufjan at his most vulnerable: His real (non-super whispery) voice, mesmerizing banjo/acoustic progressions, and most of all: it is not overproduced like Carrie and Lowell. Carrie and Lowell has autotune all over Sufjan's voice, but Seven Swans keeps it real.
