There's a demo version of Heaven & Hell but it's nearly identical, and the album version is better.
Wu Gambinos Hidden Chambers Remix (not rare)
Rainy Dayz Remix (also not rare)
There's the Iron Maiden version that has a different verse from Ghost:
Who's the Champion from the Great White Hype soundtrack (not exactly rare, but a leftover):
OG version of 260, but the only difference is the beat plays out, without transitioning into the mini skit that leads into Assassination Day:
OG version of 7th Chamber, different beat, different Ghost verse and he goes fukking offfff
Can it Be All So Simple Remix (Fresh Version)
OG version of North Star (Rae spitting over Wisdom Body):
Not Rae/Ghost but Deck, Carlton Fisk & streetlife (originally labeled a freestyle maybe?). Deck spots his verse that was supposed to be on Got My Mind Made Up but was left off
Would love to know if there's any other rarities, but I feel like I would've heard of them by now.
