Let it bang! While Travis Scott and Quavo’s joint project continues to be one of the year’s most anticipated releases, the Migos rapper takes on La Flame’s “Butterfly Effect.”

During a recent Migos concert, DJ Durel premiered Quavo’s “Butterfly Effect” remix, which features a scathing verse from the Atlanta rapper, aimed at an unnamed foe.

“Little ni**a, who are you?” he asks. “Must be bulletproof / This shit bigger than you.”

It’s unclear whether the remix will feature anyone else or if it will actually be released. For now, it is only available through the live premiere video.

Quavo and Scott have been teasing their collaborative project all year. Last month, La Flame revealed that the effort would be dropping “soon,” though he said the same thing back in May.

In April, Travis previewed songs from their forthcoming project on Beats 1, following their collaborations on Drake’s “Portland,” Lil Uzi Vert’s “Go Off,” and their Young Thug-assisted “Pick Up the Phone.” Since then, they’ve joined forces yet again on Major Lazer’s “Know No Better,” which also features Camila Cabello.

Outside of their upcoming collaborative project, the father-to-be is working on AstroWorld, the follow-up to last year’s Birds in the Trap Sing McKnight. Meanwhile, Migos is readying Culture II for an October release.
