In the twenty or so years since that Cro-Mags vid, hardcore and music in general have progressed quite a bit. Not all of it is great; as always, probably the majority of it really sucks. But the Cro-Mags are a classic, foundational band of the genre, sort of the Ramones of the metal/punk crossover of the late 80s. They've had, for better or worse, a global influence that's hard to overestimate.
