“We can’t regain what went down in the flood,” Bob Dylan sang in 1974, shortly before setting off on a 30-date tour of the United States with The Band. It turns out he was wrong. Fifty years after the last encore, thanks to technology old and new, fans will soon be able to experience that historic tour again, pretty much in its entirety. Every concert (at some venues they played twice on the same day) was recorded on quarter-inch tape or cassette. Now these recordings have been digitally remastered and will be released on a 27 CD box set in September. The release will contain 431 songs, 417 of which are versions that have never been released before (a double vinyl album, Before the Flood, containing just 21 tracks, was released to great acclaim at the time). Price? £128, not bad for what will surely add up to at least 24 hours of Dylan when he could still sing.
