I f*cking hate Monster Magnet. Nebula, Kyuss, even Fu Manchu I've learned to tolerate, but Dave Wyndorf will always be my emotional dartboard.
And I disagree. Clutch definitely had an original sound. It wasn't as massive as other stoner rock banRAB in the same era, but they certainly stand up compared to the rest. They didn't have to resort to downtuning, at any rate.
