G-Unit didn't wast any time delivering new material after reuniting at Hot 97's Summer Jam in May.

The collective is prepping to release a new EP, The Beast Is G-Unit, in October, two months after the surprise release of their 6-song EP, The Beauty of Independence.

After the rap crew blazed through their hits at iHeartRadio Festival on Saturday, Sept. 21, G-Unit shared details on their upcoming effort.

"The music has changed. The production has changed," 50 Cent tells Billboard. "We're going to start using some of the usual suspects for hits, at the present moment. [Fans] are going to feel the new energy connected to it."

While G-Unit plans to recruit some of music's most wanted, they're not betting on a huge chart debut.

"My first album sold 13 million records...If the chart mattered now, I'd quit," 50 said, before jokingly walking off set. "Compared to that period, you can forget about it. The album [of mine] to sell the worst was the Curtis record, and Em [Eminem] just sold [for The Marshall Mathers LP 2, currently No. 30 on the Billboard 200] what I sold the first week on that album."

"It's getting smaller and smaller as we go, but no one's lost interest in great music."
