Yeah, one of my favourites from genre. As I think thrash metal is mostly trash metal - it's weak in lyrics, in originality and good drumming, as well as it has really weak guitars tone, there are some gems and Carnivore is definitely one of them.
I think TON is basically a 90's continuation of Carnivore. There are some songs on both S/T and Retaliation that sounds a lot like TON would do. Especially "Slow, Deep & Hard" sounds like a lost Carnivore album. Pete was Pete, no matter who played with him.
