I'll check out Disaffected if I can. I never liked Cynic. Most of the drummers I know, and plenty of other people, get a real hard on for Focus (and Human, a real drummer favorite). I've heard it a bunch, it just never really did anything for me. It's been five or six years since the last time I listened to it, and I'm sure I'll play it again at some point.
I don't hate Human, Death was a great project and they've been a big influence on my writing. I listen to everything from Spiritual Healing on. But I almost always play Sound Of Perseverance or Symbolic first. SOP in particular has Chuck's best vocals and IMO his most personal lyrics. The feeling in that album is gut-wrenching at times. That's his legacy, for me. Reading some of his other lyrics, you can almost get the sense that he knew what was coming, but on that album it's totally apparent.
