Riffology: Iconic Rock Albums Podcast

Welcome to Riffology, where a GenX and a Millennial talk about the albums from their youth. It’s more fun than it sounds…

Two nerds, a laminator, and an extremely long “warm worm” somehow lead to a deep dive into one of the darkest, driest, and most hypnotic debut albums of the ‘90s. Undertow wasn’t just Tool’s arrival — it was a statement: no gloss, no funk, no flannel. Just tight, menacing precision and the kind of sonic control that made everything else in ’93 sound like it was recorded in a gym hall.

Neil and Chris get into Sylvia Massy’s production magic, the infamous piano-and-shotgun session that birthed “Disgustipated,” and why Undertow still feels so unsettlingly alive today. They unpack the censored artwork, the Lollapalooza breakthrough, and what makes this record sound dangerous even three decades later.

If you like your riffs dry, your rhythm sections ritualistic, and your frontmen just a little terrifying — this one’s for you.
