Foo Fighters world tour stop in Manchester featured a massive surprise – the live debut of a long-lost song called “Unconditional”.

A representative for the band said the song was “partially written and demoed during home studio sessions years 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 UK tour, and all it took was one run-through – The decision was made instantly to share it with everyone in the same way – live.”

“Unconditional” is not available to stream.
