Watch Dave Grohl join GNR on stage to play "Paradise City" live

BottleRock's 2021 edition went down this weekend in Napa Valley, and Guns N' Roses were the latest band to fall victim to the festival's strict 10pm curfew policy.

The rockers closed out Saturday night (September 4) with a monstrous two-and-a-half-hour set and brought out Dave Grohl for their last song, "Paradise City." The Foo Fighters frontman was having a blast contributing guitar wailing and backup vocals, and then the stage sound got cut midway through the song. While the move was because of the curfew, it didn't stop the band from enthusiastically finishing their performance, and Axl Rose got help from the crowd, who screamed the lyrics along with him.

The Napa Valley Expo curfew is so strict because the grounds are located in a residential area, and the main stage faces homes. It came to be when neighbors complained about the sound after Bottlerock’s inaugural year in 2013.

GNR is in good company. The festival's other curfew-breakers are The Cure in 2014, Foo Fighters in 2017 and Neil Young in 2019. The Foos were the final headliners on Sunday (September 5) and managed to finish their set before 10pm; however, Grohl now holds the infamous record of artist with the most BottleRock curfew breaks.
