Primitive Man - Scorn
http://primitivemandoom.bandcamp.com/track/rags
Hailing from Denver, CO with loads of feedback and more depression and negativity put onto one record than a normal human being should be exposed to. This album was just re-released from Relapse as well, so pick it up.
Cannibal Corpse - Butchered at Birth
https://www.youtube.com/watch?v=OtkPxffMrCo
This band needs no introduction, everyone and their grandmother has heard of Cannibal Corpse. Butchered at Birth is hands-down my favorite record of the Barnes era (although closely followed by Tomb of the Mutilated). Death metal the way it should be done with some grooves of their own thrown in the mix. Who knows where death metal would be today without this band.
Machine Head - Burn My Eyes
https://www.youtube.com/watch?v=euqtwPVuB5g
Yeah, this band turned rap metal in the later 90's and yeah they've recently started releasing decent metal albums again but Machine Head's first two records, Burn My Eyes and The More Things change are essential. Beyond influential in metal and hardcore. Try to tell me the last minute of the song "A Thousand Lies" doesn't make you want to rip someone's head off.
Thats it, dorks. Just in case you've been living under a rock for the past two decades check these bands out.
