Recorded with no sleep on garage band. Yes I know some of the vocal lines are fuzzy and weird, but I tried my hardest with a dying voice on crappy software with an idea I wanted to do.

Never listened to Bon Iver but those harmonies are awesome!
It's kinda weird hearing it A Capella but you make it work really well.
Also I did a similar thing with Supermassive Black Hole, quite late at night, overdubbing is loads of fun, wish I was better at singing in general XD
