Go to Gods of Metal, not MassMetalFest...

[Skyclad Lad]

... seeing as 98% of the bands on the latter bill will either be 3rd rate death metal bands, hardcore-gone-Goteborg poop, watered-down "tough guy" metalcore (ooooooh, I'm so intimidated!), or Dillinger Escape Plan wannabes who think they're "extreme" because they learned how to play blastbeats last week (and now feature two, yes TWO, drum-beats in their repertoire)! You can masturbate to pictures of Cristina and Angela online, chaps, without spending $40 or whatever the fee is to catch a glimpse of them from 30 yards back.
And.. AND, my sources tell me that the Palladium serves piss-weak American beer exclusively! Not even the mediocre likes of Guinness or Newcastle Brown...

Halford, though, IS worth catching, because who knows how much longer he'll be playing? Primal Fear is excellent, as well- and I LOATHE power metal, so they must be doing something right.
Amon Amarth are fun, mead-swilling louts.
I'm Welsh, and so I'm right. Always trust a man who listens to Skyclad.
