Piano duo pieces that sounds rather jazzy

[franz_]

I regulary play in piano duo, and we've build a small repertoire with jazzy sounding pieces, but we're looking for new discoveries. Someone knows good composers/pieces? It can be 4 hands or 2 pianos. We also like to play compositions on 'famous' themes, as long as they sound a bit jazzy.
Kpustin f.e. is a perfect composer, although he didn't write a lot for piano duo.
Thank you.
