I would say that music was the biggest inspiration in the making of this multiverse, and a lot of it. But here are some of the biggest influences:
The Normal Album by Will Wood
Spirit Phone by Lemon Demon
An Awesome Wave by alt-j
Basically every AJJ album, but especially the song "Children of God"
1981 Extended Play and Razzmatazz by I DONT KNOW HOW BUT THEY FOUND ME
Drunk Like Bible Times by Dear and the Headlights
Dark Glow by the Choir Vandals
Mass Teen Fainting by Plumtree
A History of Public Relations Dilemae by the Petrojvic Blasting Company
Good News for People Who Love Bad News by Modest Mouse
