I really like that little repeated motif that drifts in and out throughout the arrangement, it's almost got a Gershwin mood to it. I don't think I've ever heard that song played with that particular mood before, it's got an ominous quality about it. You are also correct about the arrangement of the soloists, they don't stand out as "hey, I'm soloing now", but fit in to create a cohesive whole.
It's an interesting album, think it will take several spins to really sink in.
