In November 2018, American rock band Greta Van Fleet—riding the wave of their debut album Anthem of the Peaceful Army, released a month earlier and immediately topping Billboard Rock Albums—delivered an intimate concert at HD Radio Sound Space at KROQ, the small Los Angeles studio where live sessions take place before 100–150 attendees. Their 30-minute set, captured in high quality, embodied their first major American tour climax, where Josh Kiszka's guitar riffs merged with Jake Kiszka's vocal power in a minimalist format to evoke warm resonance among those present. As part of the promo campaign, this performance highlighted Greta Van Fleet's role in reviving classic rock, turning the studio into a space of nostalgia and energy.
