A group consisting of Nas' brother Jungle and fellow friend Wiz.
He also said "Who's the next label I'ma bury?/CEO's, rappers and A&R's go to the rap cemetery," which indirectly implies that of Roc-A-Fella.
Overall, Nas as well as Wiz and Jungle rhyme with threatening messages, with "Y'all talk shit but I smell fear, mothafuckas" at the end of the verses.
The album had 2 songs dissing Jay-Z, with “Quick to Back Down” and “Bravehearted” featuring Nas.
It is apparently Jungle's response to Jay-Z dissing him, Nas and Jaz-O on Blueprint 2 that previous year.
