I saw Nothingface at the first Slayer I didn’t walk out on, because there was no re-entry and Pantera was headlining.
I was just never a Slayer fan growing up and it wasn’t until the last decade I even started to enjoy them. Now I have no problems with them, they just aren’t on my “I need to catch up on all this music” the same way Megadeth or Anthrax are. And Testament is before either of those three bands, for me.
That said, I’ve listened to Slayer enough at this point to know I barely give a shit about anything without Lombardo on it.
