During a performance at the Acoustic 4 a Cure IV benefit show featuring Sammy Hagar & Friends, Dave Grohl and two of his Foo Fighters bandmates, drummer Taylor Hawkins and keyboardist Rami Jaffee, performed a new song, "The Sky Is a Neighborhood."

Before beginning the song, Grohl told the crowd he decided on the way to the show that they would debut it, adding, "We've never played this song in front of anybody."

Check out the fan-shot video above.

The Foo Fighters' last studio album was 2014's Sonic Highways.

The band is set to tour Europe this summer.
