If the original analog tapes had shedding problems you might get only one shot at playing them back after baking them. In an oven. And you'll still have part of the music shed onto the tape head and other parts of the playback machine regardless.
I have no idea if this is why in this case, but for a lot of 70's and 80's music that was recorded to analog it is a huge issue (some tape brands [Ampex cough cough] more than others).
Also, this record sounds pretty interesting.
