This is a bunch of Margot videos and interviews mixed together all in HD. There are live songs, acoustic songs, interviews and some secret songs! True margot fans will appreciate this!
Regarding the comment at 23:40, I hope you learned nothing from the issues with Animal, because there's nothing to learn except that some (most) people are stupid. You probably already knew that.
I will point out that it unfortunately does seem that something was "learned", because what I hear in later music sounds more like the stuff by preferred by Epic over actually epic masterpieces like O' What a Nightmare.
