You know a concert is going to be epic when the god of thunder himself kicks it off. This past weekend, house music DJs Chris Lake and Fisher shut down the infamous Hollywood Boulevard to hold a historic concert, which became even bigger when Chris Hemsworth’s voice boomed through the speakers.

“Get ready folks because this ain’t a f*ckin’ rehearsal,” the Marvel actor starts off as thousands of fans scream and shout in anticipation. And the Australian icon did not hold back, launching into a “story time” about Lake and Fisher.

“Once upon a time, two little wizards dreamed bigger than their wands that they could shut down a land like Hollywood Boulevard and throw an epic party,” Hemsworth then continued to throw jokes at both parts of the duo as he described them as “one with an extremely massive head, perfect for dreaming, and the other was as bald as a full moon in the sky.”
