"The 13 reel-to-reel, analogue master tapes were discovered in cardboard box files in a run-down hotel in Kensal Rise, north-west London, the modest lodgings where Bob Marley and the Wailers stayed during their European tours in the mid-1970s"

apparently the Stones lent a portable 24 track to the Wailers; the tapes recovered in horrid condition, and painstakingly restored/digitized. Article in The Guardian ... Yesterday was Marley's birthday ... happily anticipating release of this live stuff.
