*searches music collection so I can namedrop a really obscure band to show how cool and underground I am*
Ahh, nope, nothing...
Well, seeing as I've never heard them mentioned on this forum (they're not obscure I promise) I reckon I could consider them as under rated. So without futher ado, I present to you:
STRAPPING YOUNG LAD!
Check 'em out. They fucking rock.
EDIT: I am gona name drop an obscure and underrated band actually. Orange Goblin, if you like stoner metal, have a listen.
I also think Down and Corrosion of Conformity are pretty under rated... Well maybe not Down, but Corrosion of conformity definitely are.
