Well, it took 6 1/2 years, but someone is finally going to review this disc. I found sealed copy for $4.00 in a bookstore this past weekend. And the 5.1 mix on every song is done the same way - the full mix of the song is in the fronts and ambiance in the rears. What seems weird to me is that the lead vocals do not appear in the ambiance channels, only the instruments and backing vocals, suggesting that the album *was* remixed in some sense.
There are three engineers credited with the stereo mixes but no credit for whoever did the 5.1 "mix"
