do any of these US hardcore songs have riffs, as such, in the "Smoke On the Water" sense? Too fast, too flailed? Ach who cares, some of the rockingest rock ever rocked.
that one closer to a "lick" maybe, but crunching mightily in parts
now what is the difference between a riff, a lick, a vamp, a chord progression, and a, i dunno, guitar part? Eh?
