i thought this summed up BM pretty well. It's not easy to determine where and how Cookie Monster singing actually began. Early death-metal bands such as Death and Morbid Angel that emerged from Florida in the mid-'80s helped create the musical template that characterized the blasting sound as well as that of its Satan- and occult-obsessed sibling, black metal: fast, relentless drumming often featuring two bass drums; grinding, rapid-fire chording on guitars; squealing guitar solos; muted electric bass; unexpected sudden tempo changes; and a sense of theatricality that's inevitably threatening--"a horror film put to music" is how Monte Conner, a vice president at Roadrunner Records, sees it.
