“Which One Are You?” is a leftover from Sufjan Stevens’s 2009 multimedia project the BQE. The track was not originally included on the project due to legal issues. According to Sufjan, he “could not clear melody w/ ELP publishers. The Endless Enigma of intellectual property. One person’s homage is another lawyer’s annoyance, I guess.” Check out the continued tale of the BQE‘s Sleeping Invader below.
