Knox... that is also my favorite Soundgarden song (narrowly edging out "Rusty Cage")... but the whole album is so good (though admittedly MTV/radio killed Black Hole Sun for me two decades ago). "Fell on Black Days" and "Superunknown" are also stand outs for me.
A year or so ago I came across some old CDs that had wound up in a drawer at my mom's house. Badmotorfinger was one of them. That whole album was pretty damn good - Rusty Cage, Jesus Christ Pose, Outshined, etc. I also was rather fond of Birth Ritual, from the Singles soundtrack.
I never really got around to checking out his later solo stuff, or the Tom Morello collaboration, whatsitcalled.
