The release of Mac Miller’s new album, Circles, feels in many ways like a final bookend on his influential career, but it’s also raised questions about what—if anything—comes next. The late rapper was known as a studio rat and left behind a massive catalog of unreleased music in various stages of completion. Aside from Circles, Mac’s family has yet to offer any clarification on whether or not it plans to make any of this material available to fans. However, at least one of his longtime collaborators is hoping they will reopen the vault.

In a new interview with Genius, ID Labs producer Eric “E. Dan” Dan explained that while he isn’t sure about the estate’s plans, he’s hopeful that fans will get to hear more music.

“I have no beat on it whatsoever. His mom isn’t really interested in talking about it, and I’ve never brought it up with her,” he said. “I hope that they do, because there’s a lot of great stuff, and a lot of great stuff that’s already finished. It just needs to be put together and released. And I hope that they do. And I’ve gone through a lot of motions to get to that point. I hope that eventually they decide they want to go back and sort of comb through the archives. I would be really surprised if they didn’t want some of this material to see the light of day. There’s just so much.”

Fans and critics have hailed the release of Circles as an example of how to best handle posthumous rap releases, with the project hewing close to the sound of 2018’s Swimming and feeling cohesive with Mac’s catalog. E. Dan noted that it was more or less taken straight from a playlist on Mac’s laptop, and the prospect of additional posthumous releases raises concerns about Mac’s wishes for his music’s presentation to the world.

However, E. Dan said that even Circles may not have materialized if Mac hadn’t passed away.

“I don’t think that I felt like at the time that Circles was actually going to be a thing,” he said, “because none of the other albums that he worked on simultaneously, whatever album he was doing, ever became a thing. It just became a folder on the hard drive… I think even Jon [Brion] said this in an interview recently, probably he would have just done a whole new album on tour and totally forgotten about it.”

Genius previously explored how the estates of Lil Peep and XXXTentacion handled the rappers' respective posthumous albums:

As E. Dan noted, many of these decisions don’t have a simple solution. “I think it’s impossible to not be left with questions,” he said. “But I also know that we don’t know. We don’t know where this project would have ended up, and not even Malcolm would have known until it was done.”
