In December 2018, American rock band Greta Van Fleet—from Frankenmuth, Michigan, and riding the wave of debut album Anthem of the Peaceful Army, released two months earlier and debuting at No. 3 on Billboard 200—performed at KROQ Absolut Almost Acoustic Christmas, the annual holiday concert by KROQ radio at The Forum in Inglewood, California, sharing the bill with Florence + the Machine and Smashing Pumpkins. Their 45-minute set, captured in high quality, embodied their American tour climax, where Josh Kiszka's guitar riffs merged with Jake Kiszka's vocal power in a minimalist format to spark euphoria among 17,000 attendees. As part of their first major headlining year, this show highlighted Greta Van Fleet's role in reviving classic rock, turning the arena into a space of nostalgia and energy.
