Green Day headlined Day 1 of the 2025 BottleRock Napa Valley festival, with Justin Timberlake, Noah Kahan and more to follow.

For the first time, East Bay alt-punk-rock band Green Day performed at the long-running BottleRock music festival in Napa. Lead by singer-guitarist Billy Joe Armstrong, the group opened with their 2004 single “American Idiot” — its lyrics now tweaked to oppose the “MAGA agenda.”

Green Day ripped through a powerful set at the BottleRock Napa Valley festival, with a special appearance from Flavor Flav.
