Do you have any takes speculating on what inspired particular tracks?
I have a theory that Eat that Question is inspired by Supernaut by Black Sabbath. Frank was quoted as saying Supernaut is his favorite song, and I believe he's also said Eat the Question is his favorite of his own. They both are centered on a main meandering riff rhythmically focused on the downbeat, and which repeats throughout the track but separated by jammy sections. Normally that wouldn't be enough to say it was inspired, but because Frank loved Supernaut so much, it seems likely to me.
