50 Cent and the rest of the G-Unit crew were in Vegas this weekend to play at the iHeartRadio festival.

The gang is releasing its second EP in two months this October (The Beast Is G-Unit will follow August's The Beauty of Independence) after reuniting at Summer Jam in May.

"The music has changed. The production has changed," 50 told 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."

But don't think 50 has high expectations for album sales.

"You know what you have to do to sell a million records now?" he asked. "My first album sold 13 million records...If the chart mattered now, I'd quit. Compared to that period, you can forget about it. The album [of mine] to sell the worst was the Curtis record, and Em just sold [for 2013's The Marshall Mathers LP 2, currently No. 30 on the chart] what I sold the first week on that album."

Earlier this month, 50 spoke about the new releases.

"It's broken into two pieces," he said. "The Beauty is the first half, The Beauty of Independence, and then The Beast is G-Unit, the second half."

Though there are just six tracks on The Beauty of Independence (it's unclear how many will be included on The Beast is G-Unit), the group estimates that they recorded close to 40 songs for the project.

These two EPs serve as a sort of comeback for G-Unit, whose last studio album T.O.S. (Terminate On Sight) was released six years ago.

"I got something to prove, we're gonna make some music," 50 said regarding G-Unit's comeback. "Music still means a lot. It's not about money...it's about relevancy, to have music that really means something in this time period."
