One of the more accessible Gentle Giant albums (relatively speaking) gets two terrific surround mixes by Steven Wilson that really highlight the superiority of surround sound for complex music. As good as the 5.1 mix is, for me the definitive way to listen to this album will be now be the atmos mix. It really opens up the instruments and vocals, providing a full 360 degree, hemispherical listening experience. I have a 7.2.4 atmos setup with separate amplification for each speaker pair, so it's pretty easy to listen to the channels in isolation. What struck me about the height channels is that they are not continuously engaged in an ambient way; instead at various points in each song, vocals, instruments and sounds are strategically placed to enhance the music. Sometimes these are used to support sound in the horizontal plane (which elevates the sound stage) but in many cases they are used as the sole source which clearly places a vocal, sound effect or instrument above you. Often these sounds gently pan back and forth, right to left, and other times a sound might appear only in one or both front or rear height speakers. I also found the additional rear surround channels made the 360 degree horizontal sound field more seamless and convincing. Clearly this mix was meticulously designed to accentuate the music to maximum effect. For the mixes and excellent fidelity, an easy 10 for me. As to the packaging, I do have a couple of minor gripes. The included booklet contains no photos or additional info - just the song lyrics. Contrast this with the booklet included in the DVD quad release - it includes song lyrics, photos and comments from the band members on the album. Why something like that wasn't done for the new release is mystifying. Also, for a relatively short album (well under 40 minutes) it's a bit disappointing that more previously unreleased or live material wasn't included. But with so many different mixes provided in lossless, and at this price point, it's hard to complain. For any Gentle Giant fan, this is a must own.
