I'll quickly say this a great album and well mixed for 5.1, and if you're looking to buy this you probably already know that.
Now, the disc format - it is a DTS Music Disc, in other words it is a redbook CD with 5.1 DTS track on it. You will need a DTS capable decoder connected by SPDIF (optical or coaxial) to a standard CD player or DVD player. If you play this in a standard CD player connected by a stereo analogue cables to a standard amp you will only hear white noise.
It is NOT a DVD-Audio disc, as Amazon have stated. I repeat, it is NOT a DVD-Audio disc.
I hope this helps clear up Amazon's very confusing and inaccurate description.
