Dave Lombardo also says y'know a bit, but I did listen to this
episode. He's really honest, and it's kind of a depressing listen. He was a really pure musician, and he trusted people on business stuff to focus on drumming and writing drum parts. As a result, he is by far, the most technically accomplished member of Slayer.
Some combination of the other members of Slayer and managers cheated him out of his publishing cuts. Imagine any classic Slayer song without what Dave came up with. It's gutting to discover.
