This Wednesday at 4 p.m., a Chicago veteran and a Harlem rapper on the rise will bring two worlds together on what will undoubtedly be a memorable episode of "RapFix Live." A$AP Rocky will make his return to the red couch with MTV News' Sway Calloway, while Lupe Fiasco makes his official debut on the show.

Since the last time he appeared on "RapFix" with Young Jeezy and Big K.R.I.T. back in November, A$AP Rocky's star has only continued to rise. On the heels of his critically acclaimed Live.Love.A$AP. mixtape and his $3 million record deal with Sony, the Harlem rapper has continued to extend his influence in the hip-hop arena, commanding guest appearances from artists such as Drake, Kendrick Lamar, Waka Flocka and Bun B during his own sold-out shows and rocking festivals like South by Southwest and Coachella.

One of [article id="1675803"]MTV News' 2011 Hottest Breakthrough MC[/article] contenders, A$AP is currently at work on his debut album, Long.Live.A$AP., which has already spawned the Hit-Boy-produced single "Goldie" and an accompanying video that was shot in Paris, with the fashionable rapper decked out in his finest Alexander Wang gear. In between his own music and promoting his rowdy A$AP Mob, Rocky still finds time for features, including a recent appearance on [article id="1682987"]Swizz Beatz's "Street Knock"[/article] single.

Lupe Fiasco, a legend in his own right, will appear alongside Rocky on the couch, and we won't be surprised if the two rappers bond quickly, as both are known for fiercely championing individuality in their music.

In the next few weeks, the Chitown rapper is expected to release Food & Liquor 2, a sequel to his fan-favorite debut album, Food & Liquor, which has been years in the making. Lupe has confirmed that the project will be a double album, showcasing his work "without industry constraints." Also on the radar is his joint album with Pharrell, which Lupe and the Star Trak producer have already begun recording.
