Dazed and Brutal
Yall About to Witness
I go by what they sound like more to me (which is straight-up heavy metal/NWOBHM).
End discussion now.
But thats not even what they sound like. They were much more gritty than any of the other NWOBHM bands of that time except for maybe Motorhead. And they had a sloppy thrash sound that would hold typical for first wave bands that followed (Bathory, Sacrofago, etc.).
