Migos released their latest mixtape late last week. The 18-track freebie is the Atlanta-based trio’s first project since No Label II, which was released back in March. It features beats from frequent collaborators like Zaytoven and Cheeze Beatz.

It’s unclear if any of the singles will appear on their forthcoming debut album, but the group is confident they have plenty of potential chart toppers stored up.

“We got a vault full of music. In fact, we’re in the studio as we speak. Right now we have 90 songs completed, but we have hundreds in folders ready to be finished, it don’t stop man,” boasted the group during an October interview with HipHopDX. They also promised a new flow after their last caused controversy over its origin. “We got a new flow coming out soon. They won’t be able to do this one though. We in one lane. Soon as they think they can get in ours, we just hop into another one.”

Quavo, Takeoff and Offset made a few fans out of their rap counterparts in the process. Q-Tip, former member of the legendary rap group A Tribe Called Quest, praised the group’s latest mixtape recently on Twitter and compared Migos to earlier southern acts like Uncle Luke and Geto Boys. “Man, y’all who hating really need to hear the mixtape. [Them] boys got bars,” wrote Tip. “These boys tha truth.”

As successful as they’ve been in recent months, however, Migos have also been wrapped in controversy regarding their violent antics and beefs with other rappers. Most recently, the three got into an altercation with GBE rapper Capo inside a Chicago restaurant, leading to an exchange of words on Twitter between the members and Capo and GBE’s Fredo Santana.
