Interesting. I haven't listened to the cd yet. I've heard the bluray 3 times now. I like the music and the surround mix still sounds good to me. Stuff in the rears most of the time, (backing vocals, instrumentation, sound effects), and some nice surround panning in places. A better mix than Hackett's studio albums normally are, and the surround is good enough to be recommended.Just to add I listened to the CD today in the package for the first time and preferred that to the surround mix not sure why.
