Ive been trying to learn this song for days on bass, and I have come to the conclusion that this song is actually impossible to play and Les Claypool is simply a wizard (original song)
An instrunmental version of this would be fucking amazing, but it's still really good as is. The vocals spoil it, but not enough to make it unlistenable. I'd adore finding more stuff like this.
Look for old prog music. It is sometimes very atmospheric and spooky. Also, do you know porcupine tree ?
