ASTROWORLD Festival is going to be epic. Not that we had any doubts.

Just a day before the inaugural event takes place, Travis Scott went to Twitter to unveil the festival's official lineup. This year's performers include big name acts like Post Malone, Lil Wayne, Rae Sremmurd, Young Thug, Trippie Redd, Virgil Abloh, and Metro Boomin.

You can check out the full lineup below. 

The festival was announced back in August, shortly after Scott released his chart-topping studio album ASTROWORLD. David Stromberg, Cactus Jack Records general manager, spoke about the event and the decision to host it in Scott's hometown of Houston.

"H-Town has an incredible rich cultural history," he said, "and we look forward to showcasing to residents from Travis' own backyard and across the globe what makes this city so special."

The one-day festival will go down Saturday at NRG Park, near the former location of Houston's now-defunct amusement park that inspired Scott's album. 

Fans can also catch Scott on the road for his Wish You Were Her Tour. The trek will continue Monday in Louisville, Kentucky, and will conclude Dec. 22 in Portland. Learn more about the shows here.
