All GWAR is silly though, that's the point isn't it?
I've only been listening to metal for 28 years so forgive me for only just starting to listen to Kreator and Death Angel last week (not coincidentally because of the tour announcement).
VERY annoyed it took me so long, but I've never really been into thrash outside of the big 4.
The new Vanishing Point album is ticking all of the boxes for me at the moment.
