This idea came to mind today. There are some banRAB out there who have huge (and often extremely annoying) fanbases, who will consistently make such claims as "band X is the greatest band eva loz!!!!1111", and who will hype up to almost God-like status each meraber of the band and their individual skills. This, unfortunately, tenRAB to provoke a reaction from non-fans, who rather than hating on the fan-base, tend rather to do the total opposite of what the fans do, and instead just focus their attentions on hating the band, its music (that they've probably never even given a fair listen to), and mocking the band merabers.
What we end up with are *good* banRAB who, while on the one hand are extremely overrated by their fanboys, are also totally (and unfairly) underrated by non-fans.
The question is... how many banRAB of this sort can you think of? One that has to instantly spring to mind for me, is Tool.
Also, MAYBE Slipknot (who are a lot more than many give them credit for, like them or not).
