Big Sean Previewed a New Travis Scott Collab and It Sounds Like a Banger

Lollapalooza 2017 wrapped up Sunday night in Chicago's Grant Park, capping off a four-day marathon of memorable performances. Ahead of Justice's closing set on the Bud Light stage Sunday night, Big Sean hit his Mike Carson-designed stage for an energetic cruise through his increasingly stacked catalog.

At one point during his set, Sean gifted the Lolla crowd with a tease of a new collaboration with Travis Scott:

The track is rumored to feature production by Metro Boomin. Sean also referenced the track's possible title—"We Go Legend"—in an Instagram post on Monday:

Sean and Scott last appeared together on DJ Khaled's Grateful single "On Everything" alongside Rick Ross.

Sean released his biggest album yet, I Decided, back in February. The album has maintained some serious legs on the charts thanks to a marathon of singles and videos, including "Sacrifices" featuring Migos. The "Sacrifices" video was first released as a gift to fans who made a physical album purchase, with Sean informing them in May that they had been given access to an app that allowed them to get a look at the video before anyone else. Shortly after, the video was made available on YouTube.

This year's Lollapalooza lineup also featured Chance the Rapper, Run the Jewels, Lorde, Blink-182, Lil Yachty, 21 Savage, Majid Jordan, Arcade Fire, Charli XCX, Joey Badass, Rae Sremmurd, and so many more.
