I know this kind of release has its audience, but I barely listen to those "making of" once... and they have almost zero replay value for me. I prefer much more the live releases and, after that, good quality demos and covers, in this order.
By the way, listening to the newer live releases that Jimmy T mixed (Berlin and Wacken), I think he's making a tremendous job, totally nailing it!!
Just comparing with 2010's MSG release, despite JLB not being in his best days anymore, I must admit I'm loving the super tight instrumental performance of DT nowadays.
