As Jay-Z and Kanye West ready their highly-anticipated collaborative album Watch The Throne, the duo has released a mini-documentary featuring interviews and behind-the-scenes footage of their creative process.

In the documentary, Jay-Z looked back at Kanye’s development over the past decade.

“Kanye, I’ve seen him, he’s really like a brother to me,” says Hov. “I’ve seen him from the beginning to where he is now and to see him as a producer and how he’s grown as a producer and an artist, for me, on another level, it’s enjoyable. I’m watching the guy I pretty much mentored become his own guy with his own opinion, it’s fantastic.”

The documentary also shows a young Kanye West predicting his future success in 2002, telling Rap fans to get ready for his takeover. “My album, y’all gonna see, I’m gonna take it to the next level,” he warned.
