In many works of Pat Metheny very often you can hear instead of improvisation the strict musical order that is more belong to a classical music than jazz. Hence some of his pieces you can also relate to a modern classics. Check his "Secret Story" album where you won't ever miss Mozart...
You should also check the solo works of Roger Eno who I think took a lot from post-classical pianist Skryabin.
