The All 6’s And 7’s Tour is shaping up to be a very special one for fans. The surprises keep coming, as fans in Eugene,OR were given a bonus live performance from Yelawolf of “Worldwide Choppers”. The Shady Records artist shared the stage with Strange Music for a one night only event. Fans weren’t the only ones excited to see Yelawolf though. Kutt Calhoun tweeted this photo of himself with the Alabama MC backstage after his performance. With so much attention swirling around Strange Music, there’s no telling how many more collaborations we could see. Kutt Calhoun’s Red-Headed Stepchild is slated for a summer release, could a Kutt Calhoun and Yelawolf collabo be in the works?
