There aren't any sound samples on the internet. I took a chance when a Japanese seller I was already ordering from had a copy for sale. Audun Strype did a good job on the recording/mastering.
PS It's not a gatefold digipack as the Discogs page states, but a non-gatefold mini-lp (hard cardboard, not laminated) with a booklet (3 pages colour photos, 4 pages Japanese liner notes, 1 page english liner notes).
