There are a few types of brutal death metal. One was pioneered in the early 90s in New York by bands like Suffocation. It emphasizes technicality through rhythmic interplay and includes fast blasts, tremolo riffs, some slams, and breakdowns (not ridiculous ones, though). The other (and less popular) version originates in Texas and was pioneered mainly by Devourment on their debut, Molesting The Decapitated. It features a murky guitar tone, less speed and technicality, and more groove and slam riffs. At times it can sound almost like really heavy, percussive hip-hop(!). Death metal is invariably "brutal" music...but in the context of the subgenre of death metal itself, there are enough bands playing BDM to delineate it further into its own "sub-subgenre." If that makes any sense...
