Brutal death metal developed by combining certain aspects of the song structures of grindcore/goregrind with death metal but it should not be confused with deathgrind (grindcore that is very close in form to, and maintains the complexity of, death metal) because it has nothing to do with hardcore punk. The bands in this genre are often categorized as technical death metal. As of now there is a hairline boundary between brutal death metal and technical death metal. Brutal death metal is associated with bands like Cannibal Corpse, Deeds of Flesh, Disavowed, Disgorge (US), Krisiun, Nile, Skinless, Suffocation and Wormed. The death grunts are very low-pitched and the lyrics are often, but not always gore related. In addition, the guitar riffs are usually slow chunky grooves or hyper fast and down-tuned, often with pinched harmonics. Typically, if guitar solos are played, they usually make large use of tremolo picking, varied arpeggios, and wailing harmonics. The drumlines are usually highly varied in style, ranging from slow rhythms to churning blast beats, often including seesaw "hyper blasts". The sound production on most albums in the brutal death metal genre usually have a very dense sound. Keep it Brutal death guy's!!
