yeah really. blastbeats weren't used in metal until 1989. up till then, it was strictly a hardcore punk/grind thing.
Your right.
The first use of blast beats is thought to originate with D.R.I's "No Sense" on their first LP (1983) and Beastie Boys "Riot Fight" on their first EP, Pollywog Stew (1982).
