i think the less guests the better but still a nice lil brainstormer scarface was the first to come to mind as i see you also said so props on that
1. scarface
2. busta
3. az (just for the reunion aspect and they've got the most classic history of damn near any 2 emcees)
4. pharoahe monch (picked it cuz i saw someone else did and i agree it would be a great collab)
5. redman (just feels like it would work somehow, maybe do a weed song)
i'd also like to see some outside producers, salaam remi is hot but less of him tends to be more. kanye, just blaze, and primo need to contribute. and a shot out of left field with black milk or madlib or someone would be hot too. and then the banger from dre.
