I just found a Nuclear Assault concert from 2015 on YouTube. They sound just as good as they did 30 years ago. Possibly the best band from the thrash metal era
I wouldn't even use great to describe them. Good band, not great and far from being one of the best. Game Over is the best thing they did, a solid 3.75/5.
I love everything they released up to Handle With Care and saw them live many times back in the day. John's vox can be kinda abrasive at times, but they were great live.
