Local H are far more than a post-grunge band. They have epic prog material like the song What Would You Have Me Do?, the groovetastic stoner rock of Buffalo Trace, the spacey-ballad Hand To Mouth, etc. While their singles may hint at something slightly post-grunge they're far more. In fact in all of their eclecticness I'd say they're more musically collected and accomplished than most tripe that gets talked about on rab.
As for banRAB that seem well cherished that I absolutely hate Rage Against The Machine, The Mars Volta, Between The Buried And Me, At The Drive In, and The Fall Of Troy all come to mind.
