I should mention that the 5.1 channel DTS version requires a DTS decoder and at least 4 speakers. The entire album reminds me of Pink Floyd's song Learning to Fly . This is probably because the style of music on this album is very much like Pink Floyd. Alan Parsons is even known for engineering one of Pink Floyd's albums, their famous Dark Side of the Moon . Overall, the album has excellent bass, although I think it's somewhat smoother sounding on the DTS version.
Vocals are extremely clear, crisp, and immediate sounding.
Acoustic guitar is spot-on, although slightly exaggerated in level at some points. Sound effects are used to great effect just like on a Pink Floyd album and overall make the album sound very cohesive in its theme of flight. The opening and closing acoustic guitar tracks Blue Blue Sky make for a nice way to tie the album together more fully. On the regular 2-channel mix, it's centered up front. The song Cloudbreak is an instrumental and one of my personal favorites.
