When it comes to hip-hop hustle, Ace Hood is the hardest out. Today (April 11), the Florida MC is going to bring his hustle to "RapFix Live."

As a rising star in DJ Khaled's We the Best camp, Ace Hood dropped his debut Gutta album in 2008 and followed up a year later with Ruthless. In 2011 Ace made his biggest impact when he released his third LP, Blood, Sweat & Tears. The album's lead single, "Hustle Hard," became an inescapable street anthem and even spawned a remix with Rick Ross and Lil Wayne.

The fiery MC didn't rest on his laurels, either: Over the course of the past year, Ace released four mixtapes. His latest tape, Starvation, came after the tragic death of his daughter. Hood chose to pour out all his emotions throughout the mixtape.

Top Dawg Entertainment's Schoolboy Q will also appear on "RapFix Live." The L.A. rhyme slinger has emerged from the same camp that launched Kendrick Lamar and Jay Rock. In 2011, he dropped his debut, Setbacks, and in January, Schoolboy released his second independent album, Habits & Contradictions. Then in March it was announced he signed to Interscope through TDE. Over the past several months, Schoolboy has risen as one of rap's most promising young talents.

Fans should also tune in to "RapFix" to see an exclusive MTV News interview with Nicki Minaj's Roman Reloaded executive producer, Safaree "SB" Samuels, and catch a sneak peek of MTV's new late-night weekly talk show "Hip Hop POV," premiering tonight at midnight ET.
