Unus Annus Season 1 You Made Beautiful Music for The Barrel... But Only One Could Win
A series in which Ethan Nestor and Markiplier embarked on a year-long journey creating and releasing one episode for each day of its run, before following through on a promise for it to be completely deleted live in front of millions of fans at the end of its first year. All in an attempt to emphasize the process of grief and mortality, helping many to remember their deaths.
