Dead Star would get a huge reaction no matter if you know that one or not. Kinda like SS, that song always get a huge reaction and I feel like 50% of the people don't know that one. Or like Unsustainable at RiP show this year, nobody knew that one and it had big moshpits
I think Matt and the rest should make a difference between those rarities and some pop/acoustic/slow songs. Fast, aggressive songs will get a huge reaction every time and hardcore fans would be happy
