The Machine Gun Kelly Lost Americana Tour rolled through Hollywood Casino Amphitheatre bringing a sold-out crowd that had enough energy to keep fans on their feet from the first opener to the final song of the night.

Mod Sun kicked off the night with the job of warming up the crowd and absolutely crushed it. Between vocals, he was dashing across the stage, head banging, and looking like a mad man in the best way possible. Opening with songs like “Mirror,” “2 AM,” Mod Sun’s insane energy immediately had the crowd on their feet. Sure, many fans may have been unfamiliar with his music, but every single fan was bumping along to each track. This was peaked when he announced how obsessed he was with our crowd, already knowing how much fun the full lineup would have.

Wiz Khalifa took that momentum and turned it up another level. He hit all of the fan favorites, “Roll Up,” “Black and Yellow,” “See You Again,” and “Young, Wild & Free,” the perfect mix for a nostalgic summer show. It of course reminded everyone why he’s been a huge name in the scene for over a decade. I myself saw him at the same venue just about ten years ago. The crowd sang along for every lyric while all sparking their lighters and putting the venue in a cloud. It wouldn’t be a true Wiz Khalifa set without it. To finish off his set, giant inflatable joints were thrown off the stage into the crowd. A few lucky fans were able to go home with the coolest concert souvenir!

With every seat filled and the lawn absolutely packed, a roar spread across the venue as Machine Gun Kelly finally took stage. Fans of all ages filled the venue, from longtime supporters to younger listeners, even a few kiddos that their parents brought along for the show. Regardless of how they found his music, everyone in attendance knew every word of his lengthy discography.

Towering over the performance was a giant inflatable Statue of Liberty head with a joint hanging from its mouth, serving as a perfect centerpiece for the Lost Americana tour. Along with bursts of pyro throughout the night, the production on its own matched was impressive. The setlist pulled from just about every corner of his career. Tracks like “Wild Boy,” “bloody valentine,” and “my ex’s best friend” sparked some of the loudest sing a longs of the night. His newer material fit seamlessly, helping to create his staggering 32 song setlist. During “can’t stay here,” the flashlights across the crowd lit up the amphitheater stage, and the voiced overtook MGK’s. Thousands of voices joined together is always amazing to experience live.

To keep momentum through the set, a B-stage was included, something rarely seen at Hollywood Casino Amphitheatre. This slower portion of the show brought a change of pace and created a more intimate atmosphere for fans nearing the back. The presence of Wiz Khalifa was throughout MGK’s set, long after his opening set had ended. Rather than a quick guest appearance, Wiz repeatedly returned to the stage for collaborations including “girl next door,” “everything tatted,” “MPH,” and “Mind of a Stoner.” Every appearance brought huge cheers, and it became increasingly clear that the crowd was just as excited to see Khalifa, and especially the two artists combined. By the time Machine Gun Kelly closed out the evening, the sold-out amphitheater had spent hours singing, jumping, and celebrating. The St. Louis’ stop of the Lost Americana Tour has easily brought one of the summer’s best shows.
