With dozens of greatest hits albums released since his death, it was thought that Bob Marley's back catalogue had been exhausted.
But a rundown former hotel in an unfashionable corner of north-west London has thrown up a treasure trove of previously lost recordings.
Thirteen reel-to-reel analogue master tapes - recordings which in some cases have only been heard on bootleg versions - have been discovered rotting in the building's damp basement.
They feature recordings of Bob Marley and the Wailers concerts in London and Paris between 1974 and 1978, when the singer was at the height of his powers. News of their discovery will cause excitement among the reggae superstar's fans.
The tapes were saved from the scrap heap when a member of a firm hired to clear the building in Kensal Rise alerted their friend and long-time Marley fan, Joe Gatt, to the find.
