Damn, that’s a bummer about Amazon!
If you’re only gonna get one of them, I would go with the CD. I usually prefer the vinyl releases, but in this case I feel that CD is better for the flow of the show. Without flipping sides all the time 
. Even if the vinyl looks nicer. 
To my ears, the CD sounds great. The CD and the vinyl got the same liner notes.
And if you get the first release of the CD (with the first cover), maybe you can help me with this old question that I never got an answer to.
