It was a bittersweet moment Saturday night in New York's Park as the Foo Fighters played an electrifying set at the Global Citizen Festival, but also made the announcement during the show that it will be their last performance for an indefinite period of time.

Singer Dave Grohl told the audience, "We're not making a big deal out of this, but this is it. We don't have any more shows after this. This is it. We don't have any ones after this. This is the show where we play as many songs as we can in a short period of time because honestly, I don't know when we're gonna do it again, but this is the perfect place to do it right now tonight."

The Foo Fighters did make the most of their set time, rocking through nine songs and keeping the energy high throughout. The performance opened with Grohl alone onstage with his guitar, relying on the audience for backup during the opening verses of 'Times Like These' before the rest of his band joined midway through to provide the frantic closing to the song.

An impressive display of hard-rocking power followed, with 'All My Life,' 'My Hero,' and 'Arlandria' leading the way. The band did work in a few of their mid-tempo favorites like 'Learn to Fly,' 'These Days,' and 'Walk' before rounding out their performance with 'Best of You' and 'Everlong.'

Grohl admitted being torn during the performance, stating, "I wish we could play all night … but I wanna see Neil Young." He followed that with his announcement about it being the band's final show for some time. For those worried about the future, it should be noted that Grohl made a similar statement to fans in the U.K. at the end of their overseas tour and then after commentary on the Internet hit a certain point buzzing that a hiatus was coming, Grohl posted his own response downplaying the hiatus talk.

What this likely suggests is that the Foo Fighters have come to the end of their 'Wasting Light' touring cycle, and will take however much time is needed to re-energize before approaching their next disc.

Grohl would later return to the stage, as he and the Black Keys' Dan Auerbach would join headliners Neil Young for the all-star finale of 'Rockin' in the Free World.' In addition to the two musicians, members of Foo Fighters, Band of Horses, and opening act K'Naan all grabbed every available microphone to provide backing vocals on the track.
