Travis headlined at E11EVEN during the Miami Grand Prix weekend. It was not for the faint or weary ... T.S. showed up at 3 AM. He first beelined it for the DJ booth, told the crowd he'd be back in 10 and then warned people when he re-appeared, everyone "better lose their motherf***ing minds!"

He did indeed come back 10 minutes later and hopped on the stage ... the sold-out crowd went nuts.

Travis' set lasted around 45 minutes, and he did not disappoint ... with "Sicko Mode," "Antidote," "Pick Up the Phone," and "Goosebumps."

What's interesting ... Travis didn't seem uneasy about going full throttle, telling the crowd to take shots as he gripped a bottle of 1942 Don Julio. Travis was happy to throw some loot into the audience.

Logan Paul was there, and at one point he screamed, "The one thing I know about you is that you turn the f*** up!"

Toward the end of his set, Quavo jumped on stage ... they did "Dubai S**t" and ended up handing the mic to a fan who was super impressive.

Travis did not blow out of there ... he stayed until 6 AM. Prior to his performance, Travis grabbed a bite at Prime 112.

There were tons of celebs on hand ... Future, Tyga, Zedd, will.i.am, Busta Rhymes, Joakim Noah, Danny Amendola, Damson Idris, Travis Kelce, P.K. Subban, Terrence J, Teyana Taylor, Karrueche, Carnage, Alec Monopoly, and Todd English.

Travis has performed after Astroworld, but only at private events, like the pre-Oscars event and a Coachella after-party.
