I agree. I was very nervous about the music considering Kirill lent such a distinctive sound to the series, but this new soundtrack is really very, very good and captures much the same atmosphere.
I'm assuming that Kirill didn't have any input: though that assumption is just based on D:OS having reworked versions of a number of old pieces rather than being entirely new, so I figured he wasn't managing the same amount of creative output by that time.
