Listen to opening track "Boris" off of their record Bullhead. Never have two guitars sounded so fucking TALL. You have to crane your neck to glimpse the tops of their looming black heaviosity! And for some reason, they are like the Pixies of metal: completely amazing, but really just really weird. My buddy Mitch introduced me to their "Gluey Porch Treatments" years ago, and I instantly fell in love with their downtuned awesomeness. This one's for you, Mitch Sr. I hope you are good where you are.
