Foo Fighters surprised fans in New Orleans on Saturday night (May 17th), by performing at the Preservation Hall, which caused an entire city block to shut down.

The rock band spent the last several days recording at the legendary venue for their new album, which will be produced at various well-known music studios across the US.

Foo Fighters are currently recording their 8th album

Frontman Dave Grohl is directing a HBO series about the process of making their 8th album, which will also include recording sessions in Chicago, Austin, Nashville, Los Angeles, Seattle, New York and Washington, D.C.

They performed a 90-minute set, featuring hits like 'Learn To Fly, 'Big Me,' and 'These Days, before wrapping things up with 'This Is a Call,' and were also joined by the Preservation Hall Jazz Band.

Grohl hinted that a show would be happening on Twitter when he posted, "So...NOLA, what're you guys up to tonight?" along with a photograph of himself and the Preservation Hall Jazz Band's Charlie Gabriel and Freddie Lonzo.

According to the The Times-Picayune, only certain VIP guests were allowed in the venue, which included Arcde Fire's Win Butler and Régine Chassagne, as well as Anderson Cooper, who was filming for a '60 Minute' feature about the band.

Usually, musicians play facing away from St. Peter's Street, but the crowd gathered outside were able to watch Foo Fighters' performance, who faced the street, through two sets of open shutters and French doors.

"This time, I feel like we really have gotten it right," Grohl told the crowd about their stay in the city. "We stayed here long enough so we learned a little bit about the city. We made a lot of friends."
