Surprise! Less than two weeks after dropping Free Bricks 2K16 with Future, Gucci Mane shocks fans with the release of another joint project with Lil Uzi Vert called 1017 Vs. The World.

With production from Zaytoven, C Note, and DP Beatz, among others, Guwop and Uzi deliver a 7-track set that includes cuts like “Threesome,” “Fresh,” and “Secure the Bag.”

The collaborative effort is a shocker, but perhaps there was a sign of things to come. Back in September, Guwop praised Uzi during an interview with Hot 97. “I like the young people,” he said. “Maybe like 21 Savage, Young M.A. … Anything that’s hot. Lil Uzi Vert, Lil Yachty. Anybody who’s hot and the kids say he’s hot, I think is hot. That’s how I do it. I embrace anything that’s new.”

This is a big day for Gucci. Not only did he drop 1017 Vs. The World, but he’s also celebrating his engagement to Keyshia Ka’oir. Plus, earlier today, he unleashed the video for “Selling Heroin” off Free Bricks 2K16.
