Foo Fighters Play Unreleased, Unfinished Song ‘Unconditional’ Live For First Time Ever

At their U.K. tour kickoff, Foo Fighters surprised fans with the live debut of a long-lost song called "Unconditional."

The 24-song set (seen at the bottom of the page) found the rock legends observing a great deal of their catalog, playing at least one song off every album except for 2014's Sonic Highways. Beyond the world premiere of "Unconditional," other highlights included a slow version of "My Hero" and Dave Grohl performing "Under You" for the first time as a solo acoustic rendition.

It all ended with the Foos starting "Everlong" twice since Grohl's guitar died.

Is "Unconditional" a New Song?

While, technically, "Unconditional" is a new song for all of us, its origin goes back a while.

A representative for Foo Fighters tells Consequence of Sound that the track was "partially written and demo'd during home studio sessions year ago, but ultimately left unfinished."

"The band’s rediscovery of ‘Unconditional’ happened in true spontaneous Foo Fighters fashion: The song came up in conversation during rehearsals for the U.K. tour, and all it took was one run-through. The decision was made instantly to share it with everyone in the same way – live," the rep states.
