The bass playing here is more atypical and will tend to trade the riffs with the guitar or keyboard, that is why when Jon isn't multi track chanting his voice tends to sound more organizationally lonely than when in Yes. It also an issue here of sound. If you sing Counter Tenor there is no better way to give it context than to underpin it with a warm rounded Bass sound to create light and shade and give the Counter Tenor a musical "home". With that absent the voice is exposed and its lack of timbre and depth becomes clearer. In choral terms it is as if you are singing 4 part harmony with three parts with the root missing so it has no foundation.
There are occasional moments when the backing vocals respond to Jon but this is not the close harmony of Yes. In the second movement there is a rare example of the bass playing the tune and shadowing what Jon is singing, which is why it is probably the best element of the suite. Indeed I have listened to this first suite with just Jonas and Jon’s playing and singing in focus and far to often Jon’s vocal dance and phrasing is out of step with Jonas’s playing, indeed when they come together the music becomes much stronger and more powerful. Listening to the second movement where the playing and singing are in sync that sense of randomness disappears.
I do not consider myself an audiophile but as regards those last six pieces two matters stand out about the mix.
1) The Drums and Bass are very anonymous contributing to the generic sense of the music.
2) Jon's voice on several occasions is far to loud. A particular example is when the "Know" theme is introduced midway through the final piece it sounds overloud, harsh and unattractive which is only made more obvious through the back up singers who sound melodious and sweet to listen to. As someone who listens to the very best vocal performances Streisand/Krall/Sinatra et al who dominate the sound spectrum there is a real difference of quality from the aforementioned when Jon is placed in a singular spotlight. Indeed I find after several moments, rather like the Ladder in parts, the performance sounds wearing and a trial rather than seducing me into the narrative.
