Indeed, my friend, Vol.2 was a digital-only release. Full details plus a review I wrote found here:

Vol.1 is a far better collection of music, but it seems you already acknowledge its awesomeness. Vol.2 is...interesting. I liked it a lot, but it might not suit your tastes. Note the non-Asian composers in the mix.
