Eminem And Busta Rhymes' Six-Minute Battle Rap Is 'Pretty Crazy'

'They're battling each other for like 30 to 50 bars apiece,' producer Sccop DeVille tells MTV News of 'Calm Down.'

Eminem is no stranger to rap battles. But if you think top-selling records has made Em soft, think again. Slim Shady is prepping for a lyrical throwdown with none other than Busta Rhymes, and producer Scoop DeVille spoke to MTV News about it.

"[I'm] working with Busta Rhymes, I have a single coming out with him called 'Calm Down' with Eminem and that's a six-minute record where they're battling each other for like 30 to 50 bars apiece. It's pretty crazy," Scoop told us while he walked the red carpet for the 2013 American Music Awards in Los Angeles on Sunday night.

Busta first opened up about the track, which will appear on his upcoming Extinction Level Event 2 LP, in a September interview.

"I've got a six-minute record with Eminem that sounds like we are respectfully trying to battle each other in a way that you probably never heard us battle in our entire careers on a record," he told XXLMag.com. "So it's lot of real incredibly golden moments for us on this project."

The track is sure to be a highlight for all involved, including DeVille, who has built his career by logging in standout records with Snoop Dogg ("I Wanna Rock"), Fat Joe ("Slow Down") and Kendrick Lamar ("Poetic Justice").

During Sunday's awards, Scoop got to see K-Dot perform "Poetic Justice" and confirmed to us that he's back in the studio with Lamar.

"Yes, actually we're working on his new album right now," he said. "I think he's molded his sound to where it needs to be and there's a lot of good surprises for this new album. Be expecting to hear something different, something new."
