Trap duo Flosstradamus takes a step forward with their newest release, "Came Up," which finds them combining their brand of bass with an assist from Post Malone along with Key! The track also features production efforts from FKi 1st and Hawaiian producer Graves.

A wash of vocal reverb leads us in before Post plays with the hook as he sings about making it in music and the unknown future of tomorrow. He splits duties on verses and takes the first round before passing the second run-around to Key! to finish things off. "I'm just happy to have been a part of this record. Key! has been my guy from day one and with Flosstradamus it's just a perfect fit," Post said in a press release.

If you're familiar with Post's work, you will also know this isn't the first time he has collaborated with producer FKi 1st, who is one half of the Atlanta production team FKi, and who also executive produced Post's debut mixtape, August 26, as well as his forthcoming debut album, Stoney. FKi is no stranger to hip-hop and has worked alongside 2 Chainz, Young Thug, and Lil Yachty.

Thursday night, Flosstradamus performed the track for the first time during their set at Lollapalooza, bringing out Post to amplify the performance.
