More circumstantial. However, running the urls etc. trick, the National redirects to Sufjan. Additionally, Sufjan and the National's guitarist Bryce Dressner are touring a project called "Planetarium" right now (as well as Sufjan having played with the National in the past). Surely that's just a bit too much coincidence to dismiss. I posted something earlier, but no one latched on. Perhaps just less enthusiasm than I expected over a Sufjan project at the beach. Anyhow, I'll be there.
I love Sufjan, but I've read that he doesn't like doing outside festivals so I'm cautiously optimistic about it. He would be one of the most exciting gets for me.
