Big Business is that dude from Karp and that dude from Murder City Devils. They are both newer members of The Melvins, as well, playing on (A) Senile Animal. Massive, sludgy, thundering stoner rock. One of my favorite records lately. These jams WILL get stuck in your head. If you're a fan of The Melvins, Kylesa, Torche, etc... then you should certainly download this record.
