A heavy metal band. They used to rock, but now they suck.

Haven't you all noticed that they sound different? Page Hamilton sings different, too. They sound like poppy mainstream crap now. They don't even sound metal anymore. It's not even Helmet without Henry Bogdan, Peter Mengede and John Stanier. Mr. Hamilton should just retire.
Helmet used to be a good band in the early 90's. But not anymore!
