PetroDragonic Apocalypse; or, Dawn of Eternal Night: An Annihilation of Planet Earth and the Beginning of Merciless Damnation. Whole album's pretty good, but Dragon and Flamethrower are my favorites from the album.
Origin, Soreption, Archspire for some groovy brutal-tech. Gorguts and Ulcerate for some disso/avant-tech and maybe mix it up with a little tech-grind with Discordance Axis and Gridlink.
