G.O.O.D. Music was in the building as Big Sean and former member Kid Cudi joined forces to perform 'First Chain' on Friday’s edition of 'Late Night with Jimmy Fallon.' Backed by the Roots band, Sean Don and the Cudder gave a hyped performance of the anthemic track from Sean's 'Hall of Fame' album.

Speaking of chains, the Detroit rhymer rocked a huge Jesus piece necklace along with Timberland boots and an olive-colored coat. Cudi, on the other hand, kept it simple with a Nirvana T-shirt, cardigan sweater, jeans and Air Jordan sneakers.

Sean rapped about his humble beginnings in the D-Town to now rocking shows worldwide. Cudi came out midway to perform his verse and warble some harmonies.

Although Cudi is no longer a member of Kanye West’s all-star label, it’s good to see that he’s still able to maintain a cordial relationship with the artists.
