Isis is one of the worst bands in metal today. And I dislike all bands who sound like them.
Crowbar
Down
Corrosion of Conformity
Soilent Green (Sludge/Grind)
Shub Niggurath>>>>>>>>>>>>Nerurosis
What lies at the basis of that comparison anyway?
Heaviness?
Stoner doom and sludge own the shit out of thrash as well while I'm at it.
