I am writing from the memory so I may mess something up, but it was recorded on the cassette or a Mini Disc, I think. One song is from the portable recorder next to the drummer, etc. Hardly an audiophile set-up. It does convey the atmosphere well, though, so if you want "be there" feeling this is a good one.
’At the last moment, Kortes decided to tape her scheduled performance of “Blood on the Tracks.” Having only a cassette to make a board tape, the first side came out OK, but the second side was problematic.
Then she found someone had recorded the entire performance on a mini-disc. After passing copies along to Billboard magazine and www.dylancoveralbums.com, Kortes thought that would be the end of the story."
