Last week, Young Thug and Future fans were treated to their new collaborative project Super Slimey. Although the project was considered a surprise release, it wasn’t all that shocking since anyone follows both artists on social media would have known they’ve been hanging out together a lot. And anyone who knows anything about either of those guys knows they’re always recording songs. In a new interview with Complex, producer Southside talked about working on the project.

According to the “Three” producer, the sessions had a family vibe in the studio and they didn’t work off any timetable at all. In fact, they were recording songs for the project until three days before it actually dropped. But the most exciting part of the interview may be when he claimed they have more in store. “Honestly, these aren’t even the hardest 13 songs, this is just like a teaser,” he said. “They have some very very epic music together.”

Southside also claimed he once told Future him and Thug could make a project like JAY-Z and Kanye West’s Watch The Throne if they worked together.

During the interview, Southside also took the time to reflect on Seth Firkins—Future’s longtime engineer who passed away earlier this year. “I have been working in the same studio that Seth loved for the past month,” he said. “I’m doing everything I’m doing for Seth, so is Future, and so is Thug. Everything we are doing is for Seth, because he was like the third piece of our vibe that was taken away from us. Seth had a major play in this because a lot of these songs were recorded by him. Seth is still in our hearts and he’s our drive right now.”

Southside knows a thing or two about Future and Thug. Southside and his crew 808 Mafia contributed on seven of the 13 songs on the project. Southside has also produced a ton of songs for Thug (“Danny Glover”) and Future (“Fuck Up Some Commas”) individually.

When asked at the end of the interview if there’s another project coming soon and if it would be titled Super Slimey 2, Southside said: “It might not even be a Super Slimey 2, it might be What a Slime to Be Alive up next.”

Hopefully, whatever they end up releasing, it’ll feature the full versions of songs Thug has previously shared snippets of.
