Today (Sept. 20) is Area 51 Raid Day! With over two million people signed up "Naruto Run" into the government’s most secretive location, Foo Fighters have surprise-released a live EP, recorded in Roswell, New Mexico.

Foo Fighters really know how to get a party started, even when facing earthly demons like the Westboro Baptist Church. We’re talking aliens, this time around, and Foo Fighters had the perfect plan to commemorate Area 51 Day.

Back in 2005, the Foos performed at Walker Air Force Base in Roswell, near an alleged UFO crash site. Dave Grohl and the gang invited 500 fans to attend the show, all of them competition winners celebrating the release of the band’s fifth album, In Your Honour.

The seven-track EP features hits like “Monkey Wrench,” “All My Life” and “This is a Call.” A special in-flight manual was even shared by the Foos via Twitter:
