Why do you think it's "upside down"?
Maynard is a very peculiar fellow.
He often does pre-show rituals that are quite odd.
Read through some show reviews sometimes. Some of the things mentioned just might make you squint.
Have you ever listened to the song Rosetta Stoned? You probably should. Hell, I could say a lot more about Maynard, let alone any particular band he's in.
For every lock there's a key.
