One of only two Sufjan albums I enjoy. Carrie and Lowell is the other. It’s good but it’s kinda over long. 2.5 rounded up.
Love this album. Agree that it's a bit long, but I really enjoy the vocal delivery on this, moving between so many emotions and putting you right in the moment. 4/5.
Illinois is one of those albums that I forget is great until I am listening to it. Like @dbarila , I get much more out of the experimental stuff, but I feel like that disparages this a bit, because it's not like it is your typical singer songwriter fare. It is very much of the same ilk as Age of Adz and Seven Swans - melodically and thematically, it is just the bridge between. I imagine that this is the kind of music that Tim DeLaughter and Brian Wilson hear in their head.
