Shredfest, Metalligeddon, Metalocaust, Shredzkrieg, Satans Sergeants, Deathshredfuckscum, Appeasing Satan, Over 11, This one goes up to 12 and.... I'm not even trying anymore. Can't think of a metal band name in a serious context. Dunno why...
Oh and Carpathian Darkness in Satans Forest of Bludgeoning Flaming Animals.
EDIT: Scratch those. In the traditional one-word stylings of many a great metal band: Bludgeoner. Not sure if it's a real word, could be now and it should describe your sound perfectly!
