Dripping with Kajiura
For me Hans Zimmer's Dune is far above everything else production wise.A very old thread, but I really recommend trying to listen to YK at least on CD quality/FLAC and through a stereo set. I can't think of an artist whose work is produced better than hers and I think I've roughly a 1,000 artists or something I my collection. It is rare to encounter even a mediocre YK OST album production-wise.
A good stereo set will be able to convey delicate details to you. For example, I forgot the album but you are able to hear chimes ring and circulate above your head before finally disappearing. Apparently, YK had decided such an effect should be included on the track. There are many other cases of three-dimensionality on her albums. They turn into a bigger experience, like you were in a cinema enjoying a movie vs. watching the same film on a small tv screen.
Yuki Kajiura has yet to release her first work in Dolby Atmos, although I definitely agree that overall her works shine by their three-dimensionality.
