Pantera is one of those bands I missed, more or less, when they came around. They weren't a big-name metal band when I was listening to metal.* They pretty much started making the music I'd have liked, and like now, after I wasn't really seeking out and listening to metal bands.
But this one song kept coming up - Walk.
It's really what I like in a metal song. It's one I can't turn off when it comes on. If you haven't heard it, give it a try.
* Not just metal, for sure, but most of the metal I got into was when I was in high school.
