There doesn't seem to be any material not already available on previous releases, I'm sure most fans already have the Live at the Paradiso DVD and extra RFH tracks released in Japan.
On the flipside, packaging includes replica album sleeves and comes with a 96 page book with an essay/ interview by Sid Smith.
This box is already available in Dutch recordstores, if you can't wait. I did not really care for the packaging or the additional essay/booklet, so i'll skip this one
