Jay Z and Kanye West initially had a rapper/producer relationship but the pair quickly began rhyming side by side. Yeezy provided the chorus to Scarface's "Guess Who's Back?" featuring JAY Z in 2002 and appeared on Hov's "The Bounce" later that year. Hov guested on West's first two LPs, The College Dropout and Late Registration. The two eventually joined forces to issue the epic Watch the Throne in 2011.
