Aumgn and Peking O are a real test for a lot of listeners, so are they essential to the album or the part you'd skip?

Aumgn is one of the more ethereal things I've listened to in headphones. There's so much to digest in this!

There are parts of this that are reminiscent of the Grateful Dead's Drums/Space

Aumgn felt kind of meditative. Peking 0 feels like pure chaos. I think I enjoyed the former quite a bit. Not sure about the latter.

The end of Peking O sounds incredibly similar to a track on The Flaming Lips' Yoshimi Battles the Pink Robots. I wonder if Wayne Coyne was at all inspired by this album?
