Damian Lillard is a rising voice in the rap genre. With a rising voice, the opportunity to get famous voices — like Kanye West — to collaborate with you becomes available.
This is exactly what Lillard, aka Dame D.O.L.L.A., has in mind (and more), per Drew Ruiz of SLAM Magazine:
I think with us both doing music and him obviously being who he is and also being with adidas and having a shoe line, I think it’d be a cold collaboration if we did music together and a shoe together.
This answer came after a question about Lillard working with bigger names in the rap game; on “The Letter O,” he worked with artists like Jamie Foxx and Lil Wayne.
