Rappers have been singing Lil Wayne’s praises for years, but 2 Chainz’s recent “Dedication,” was so moving that it got the skateboard-obsessed rhyme animal emotional on another level.

“If it wasn’t for Wayne, it wouldn’t be / A lot of dudes in the game, including me,” Chainz spits on the song, the intro to his and Wayne’s collaborative album, COLLEGROVE. From there he takes a trip down memory lane, thanking Wayne for believing in his talent when few others would.

“I didn’t know he was doing it. It just came from nowhere,” Wayne told Genius during an interview alongside Chainz after their March 30 COLLEGROVE concert at the Tabernacle in Atlanta. “I already tattooed some [tears] on my face, but that song made a few more drop.”

To celebrate the release of the LP, the longtime friends performed an exclusive concert. After the show, they sat with Genius backstage to talk about the project, their creative process, and their unbreakable bond.
