I wholeheartedly approve of this. Clutch is basically the best band ever, and you sir are a brave man for attempting to rank 30 songs of theirs. I don't think I would actually be able to decide on anything close to a final top 10, let alone 30.
Seeing this reminded me, holy mother of fuck am I excited to pick up Earth Rocker, see them two (three...?) times in March and maybe interview one of them!
