While 2 Chainz has become one of the most reliably entertaining personalities in the pop-rap orbit, Lil’ Wayne remains a trickster extraordinaire and rap myth made flesh. A portmanteau of the neighborhoods where they grew up (Chainz in College Park, just outside Atlanta; Wayne in Hollygrove, New Orleans), Collegrove is an inspired pairing, from the quiet menace of “Gotta Lotta” (produced by Cash Money legend Mannie Fresh) to the mentholated reggae of “MFN” (produced by Atlantans Mike Will Made-It and Zaytoven) and the sprawling “Rolls Royce Weather Every Day,” where Wayne issues a rare apology: “I do me and love it, Lord I done overdid it.”
