One of the special things about music festivals is the unknown about what could happen when you have so many musicians in the same space ...
One of those magical moments happened at the BottleRock Napa Valley Festival when Dave Grohl joined Guns and Roses during their encore performance of Paradise City (!)
The only issue with this reunion of former foes: it happened after the fest's strict 10pm curfew - forcing organizers to cut the sound :/
Lucky for those of us who were not in Napa for the show - fans have shared footage to the web ... including the band continuing to play after the house sound was cut off
This isn't the first time Grohl and GN'R jammed - the two teamed up for Paradise City in 2017 in Oklahoma City
