The Martin's (Giles, with a little help from his friend aka Dad, George) mixed this specifically for 5.1 multichannel (Cirque's Revolution Theatre) and the resultant DVD-Audio is remarkable!! There is no comparison to the redbook layer. I've done a 24/96 stereo downmix from the disc and like it slightly more than the included PCM layer, and the redbook always finishes a distant third......but to really experience this remix you must listen in 5.1.
